Hello Ash,
Effectivenormalstress=[41,79,119,159,197,80]'; % make these into column vectors
Maximumshearstress=[34,73,97,138,173,56]';
x=Effectivenormalstress;
y=Maximumshearstress;
c = x\y
xplot = 1:200;
plot(xplot,c*xplot,x,y,'o');grid on
The idea is to fit the linear relation x*c = y in the least squares sense where x and y are column vectors.
