Hi all,

I have an excel file where I loop over a matrix and want to calculate something for each cell within the matrix. I do this with the following
Code:
<code style="margin: 0px; padding: 0px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; vertical-align: baseline; box-sizing: inherit; white-space: inherit;">[COLOR=#101094][FONT=inherit]Dim[/FONT][/COLOR][COLOR=#303336][FONT=inherit] x[/FONT][/COLOR][COLOR=#303336][FONT=inherit],[/FONT][/COLOR][COLOR=#303336][FONT=inherit] i [/FONT][/COLOR][COLOR=#101094][FONT=inherit]As[/FONT][/COLOR][COLOR=#101094][FONT=inherit]Integer[/FONT][/COLOR][COLOR=#303336][FONT=inherit]

Where <code style="margin: 0px; padding: 1px 5px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; font-size: 13px; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">Dummy</code> is a function that I wrote.

[/FONT][/COLOR][COLOR=#101094][FONT=inherit]End[/FONT][/COLOR][COLOR=#101094][FONT=inherit]Function[/FONT][/COLOR]</code>

However, the problem is that within the file I also specify which function I want to use within the loop. This specification is located in cell <code style="margin: 0px; padding: 1px 5px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; font-size: 13px; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">A1</code>. So for example, if <code style="margin: 0px; padding: 1px 5px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; font-size: 13px; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">A1</code> = 1 I want to use my own user-defined function <code style="margin: 0px; padding: 1px 5px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; font-size: 13px; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">function_1</code>, 2 is my own-defined function <code style="margin: 0px; padding: 1px 5px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; font-size: 13px; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">function_2</code> etc. Importantly, for each cell the function is the same. So I need to specify this before the loop. Otherwise the macro will be slower than necessary, because it checks for each cell which value is located in <code style="margin: 0px; padding: 1px 5px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; font-size: 13px; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">A1</code>. I tried the methodology from this Stackoverflow post by first using a simple dummy-variable and then run a new macro and replace the dummy-function with the specified functio. This doesn't work because the output of the <code style="margin: 0px; padding: 1px 5px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; font-size: 13px; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">Dummy</code>-function is <code style="margin: 0px; padding: 1px 5px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; font-size: 13px; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">1</code>.
An example of possible function is

Question How can I re-use the defined functions as a new function in a macro?
