I am trying to plot a 3D graph for t and T against Y_B. I would like the interval t to be 0.2 to 30 and the interval of T to be 600 to 850. Here is my code below:
T=600:1:850; t=0.2:0.1:30; [tm,Tm] = meshgrid(t, T); k1 = 10^7.*exp(-12700./Tm); k2 = 5*10^4.*exp(-10800./Tm); k3 = 7*10^7.*exp(-15000./Tm); Y_B = (k1/(k1-k2-k3))*(exp(-(k1+k3)*tm)-exp(-k2*tm)); Y_Bmax = max(Y_B(:)); Idx = find(Y_B(:) == Y_Bmax); [Y_BmaxRow,Y_BmaxCol] = ind2sub(size(Y_B), Idx); figure(1) mesh(t,T,Y_B) view(40, 45) grid on
The output error tells me that the inner matrix dimensions do not agree. However, I cannot see how to fix this.
