I am sorry, because I guess that my question is either very trivial (and I missed it), or without positive answer.
I need to change in a Mathcad (v.11 still, but I tried also with v.15) a matrix dimension from 3 to 2.
I have several equations, with "identity(3)" function, that needs to be corrected accordingly. I thought that the replace command would suffice to make a global change. Yet there is no way that Mathcad finds (both regions selected) the terms "identity(3)" in my worksheet, even if they are there. The culprit seems the bracket character.
Is there a way to make the find/replace command work? Thanks.
