??? Error using ==> times Matrix dimensions must agree.

I could`nt figure out how to resolve

T = 20:1:40; F= 20:0.1:40;

Ct= (-1/pi*(atan(T-33)+atan(T-27))); plot(T,Ct),grid on;

A= 0.5-1/pi*(atan(Ct-0.9)); B= 0.5+1/pi*(atan(Ct+0.1)); Cf= 1/pi*(A-B/2);

C= A.*atan(F-55);% error occurred here

Please help me solve the project

Answer 1

A is 1x21 array, F is 1x201 array. That is why.

Answer 2

[Bhagirathi]

I need to add Cf and C. How would i resolve the error? My desired output would be looking like a step function. Please help me in figuring out the soln of the error

??? Error using ==> minus Matrix dimensions must agree.

Error in ==> testrun at 10 Cf= 1/pi*((A-B/2)-C);

Well, the error again is the matrix size mis-match. Most of your matrix is 1x21. Check your F. Should it be F=20:0.1:40 or should it be F=20:1:40. If latter, problem solved.
