A very simple task to find min of each column of a matrix but something strange happening.
I would call this a strange bug.
I have no idea why it would occur. All I can do is provide a simplified example and some observations in case you intend to bring this bug to PTCs attention (good luck).
The bug shows up if the matrix has more than 1 column and is seen in all columns which include at least one text entry.
A crude workaround could be to always call the routine with MatrixCol.min(stack(...)) instead of just MatrixCol.min(...).
Indeed a very strange bug.
BTW, don't put M <-- stack(M) as first line in your program as if you do it will fail in any case when text is involved.
Here's a better workaround.
Don't ask me why it works. Of course its still a bug.
Thank you for your time and efforts. I`ve created some min.str.f() function to work around this bug.
1. What service release of Mathcad are you using?
