1. The problem statement, all variables and given/known data I would need some help with extracting two matrices from a text file into Matlab. First is the 60x3 matrix of node coordinates. Second is the 24x8 matrix of node numbers assigned to elements. I have 24 brick elements so each of the elements has 8 nodes. But there are some rows of numbers which are not the node numbers but probably some connectivity arrays and I don't want them there. According to the attached file, the first row of the second matrix should look like this: elements(1,:)=[ 1 2 3 4 13 17 24 25 ]; I don't know how to write that code :( I 'd really appreciate someone's help.
