I think I know what you are talking about, but that doesn't help because I need an if statement in the formula to can test the current lin with IsNan() so I can skip it with a nop (no operation).

The prototype for IupMatrixSetFormula only has a parameter for col and nothing for lin. Is the following a typo in the HTML documentation for IUP - Version 3.30?: void IupMatrixSetFormula(Ihandle* ih, int col, const char* formula, const char* init); [in C] iup.MatrixSetFormula(ih: ihandle, col: number, formula: string, [init: string]) [in Lua] or ih:SetFormula(col: number, formula: string, [init: string]) [in Lua] On 2/27/2022 at 10:13 AM, Antonio Scuri <antonio.sc...@gmail.com> wrote: > "so it's not a useful function" I think if you read the documentation carefully you will see that it is a very useful function... Also you will find out that the formula receives two parameters lin and col, so you can test the col number and return the contents you actually want in the UNITS cell. Then maybe you're not stuck after all...

Is there a way to restrict which rows IupMatrixSetFormula or am I stuck with doing it manually, cell-by-cell?
