Subject: data extraction from matrix to use in another matrix From: walter Mulvany Date: 19 Oct, 2013 16:03:06 Message: 1 of 27 
I'm writing a code for finite element analysis and I don't know how to read a value from a matrix (A) and use it as a pointer to direct me to values in another matrix.

My mistake, that matrix is wrong.

I'm very sorry to say that it did not work because it arranged the matrices.

I think that this problem is about indexing, and I don't think that I have done a good job explaining what I need to do.

yes, is column not row.

What I need to do is to go to element 1, read the value of (conn  column 2) which is 5, go to the coord matrix, find the value (5) in its column 1 and extract the x value that correspond to that location (5) from (coord  column 2) which in this case is (1).
