Say I have the matrices:
A = { 1 -2 3,
-1 1 5,
3 -2 -4};
B = { 0 0 0,
0 0 0,
0 0 0};
And I would like to apply the following logic: If a value of A is less than zero (A<B), then keep the value. If not then double the value.
My goal is the matrix
C = { 2 -2 6,
-1 2 10,
6 -2 -4};
Can this be done in IML? I am running into issues where the comparison is being treated as an ALL function.
Or, if I use a statement such as C=A>B then I am returned a matrix of binary values based on the comparison.
Thanks!
You don't need the matrix B. Use the CHOOSE function as follows:
C = choose(A<0, A, 2*A);
