Hello,
I want to set certain elements of a matrix to 1. Interestingly the following
code fills 9 elements with 1. I expected to have only 3 elements (with index
1,1; 2,2 and 3,3) filled with 1.
A=zeros(5,3)
inx=[1 2 3];
iny=[1 2 3];
A(inx,iny)=1
Using this is for submatrix but what you want is not a submatrix. In
your special case A=eyes(5,3)
Is there any way to fill a matrix with 1 where I have the indexes in 2 vectors?
IMHO only the for loop works, in general...
