If statements for matrices

If statements for matrices

If statements for matrices

(OP)
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.

RE: If statements for matrices

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
