If statements for matrices 1

[juhop]

I am quite new to Mathcad, and am wondering if there's a simple way to run 1D matrices through if statements. Currently the if statement just complains about the variable not being a scalar, and doesn't therefore process the variable.

Thank you.

You can either vectorize it or index it.

Unfortunately, the vectorize operator doesn't apply to if statements. The normal way to use if statements in conjunction with arrays is to use a program for-loop or a range variable.

eg: i:=0..3
ans[i:=if(v[i>0,3,-3)

or

for i e 0..3
ans[i<- 3 if v[i>0
ans[i<- -3 otherwise
