Hei,

I'm trying to take a look at a function that displays the ratios of 2 surfaces of a function. The code is as follows:

>> ton = 0.1:.1:60;
>> trest = 0.1:.1:60;
>> t2 = ((a1.*(trest - b1).^c1)+d1).*i.^(i.*((a2.*trest.^b2) + c2)) + ((a3.*(trest-b3).^c3)+d3);
>> [X,Y] = meshgrid(ton,trest);
>> G = (int(a*exp(b*t) + c*exp(d*t),t,t2,trest+t2));
Warning: Explicit integral could not be found.  
>> F = int(a*exp(b*t) + c*exp(d*t),t,ton,trest+t2);
Warning: Explicit integral could not be found.  
>> A = G./F
>> surf(A,X,Y)
??? Error using ==> surf at 78
Data dimensions must agree.

All the a's, i's and b's etc have all been given their respective values. The way I'm syntaxing this code is where the problem lies I think. I'm not sure how to solve the problem though :/
