Quick question about extracting a single column from a large matrix into a submatrix. Just as an example below: I want extract the second column from matrix P ( I want to pull out 2,5,8) and place it into a submatrix called A. However when I try to attempt it in this way, I am getting invalid matrix token error.
P=[1 2 3, 4 5 6, 7 8 9];
for(i=1,i<=3,i = i + 1,
A = [P[i,2]];
);
Should be really simple, but for some reason it is stumping me. Thanks for the help!
Matt's pointing you in the right direction.
Here's a more specific set of documentation on Subsetting Matrices.
The answer at the end of the book is that a subscript argument of zero selects all rows or columns.
P=[1 2 3, 4 5 6, 7 8 9];
A=P[0,2];
