Hello,
I am wondering why I am getting this display error. I have written another script using the same matrix, it's just a smaller square matrix. Can anyone help me in having this script run correctly. In the attachments is a snip picture of what I am seeing in the command window.
%%If 10 elements are used
E = 30*10^6; L_0 = 6;F = 300;SLOPE = -1/12;D = @(x) (SLOPE*x)+1; % This is the function of Diameter
