if A=1:0.1:10 and B=1:4,T=exp(A/B) , is there anyway to plot a graph of T against A?

if A=1:0.1:10 and B=1:4, T=exp(A/B) , since they are of matrices of different sizes, is there anyway to plot a graph of T against A such as using for loops?

Dear Austin, you can do it as follows:
A = 1:0.1:10;
B = linspace(1, 4, numel(A))
T=exp(A./B);
plot(A, T), xlabel('A'), ylabel('T')
I hope it helps. Good luck!

Use bsxfun to do the division. Here is a small example:
A = 1:0.1:10;
B = 1:4;
T = exp(bsxfun(@rdivide,A,B'));
plot(A,T)
Note, four lines have been drawn, the plot it just scaled to the very large values so the rest appear lumped at the bottom.
