Hello,
I have obtained a matrix for a stress component syy that is 801x180. This stress depends on another stress s that takes integer values from -400MPa to 400MPa (801 values) and angle of a crack from 0 to 179 deg (180 values). How can i plot that?
Feel free to suggest cool ways as well. 20% of my mark is nice presentation. Thanks
i = -400:1:400;
j = i + 401;
sigmap(j) = i;
k = 1:1:180;
phi = pi*(k-1)/180;
%using all those defining:
syy(j,k)
