r=[rmin:rmax];t=[tmin:tmax];AT2=T1*r.^((gamma-1)./gamma);AP2=P1.*r;AT3=T1.*t;AP3=AP2;AT4=(AT3.*T1)./AT2;The error saysError using ./ Matrix dimensions must agree.Error in attempt11 (line 24)AT4=(AT3.*T1)./T2A;MATLAB: A line of the code is T4=(T3.*T1)./T2 where T2 is a 1×10 double matrix and T3 is a 1x6double matrix. How to reshape one of the matrices so that the line of code works enabling me to get values of T4. T1 is a 1×1 double.

That is so excepting when you get to
underdamped = exp(-t./T1)*(B1*cos(omega*t.)+B2*sin(omega*t.));you're trying to multiply the damping by the waveform all of which are vectors. You're missing the "dot" on the .* to do element-wise multiplication of those two. "+" works without a ".+" operator as the operation is element-wise anyway and there isn't a secondary definition as matrix multiply overloads the "*" operator so have to have two different ones.
underdamped = exp(-t./T1).*(B1*cos(omega*t)+B2*sin(omega*t));I corrected the extraneous 'dot' after the t in the omega*t terms, too, btw...
