Hi,
I have a matrix A 3x1201 and a vector B 3 elements. (A and B can change size but B will alway have the size of A row's).
B contains the indexes of the column in A I am intrested in.
First element of B is the index of the first row in a
Second elemnt of B is the index of the second row in A.
Third elemnt in B is the index of the third row in A.
How do I store in a new vector?
I Attached A and B to the post.
Thank You everybody!
In short I have to store in a new vector the elements:
A[1,1118]
A[2,1124]
A[3,1132]
B =
1118 1124 1132
