what is "Error using ==> mtimes Inner matrix dimensions must agree."

The question says write a matlab code to draw praph of F(t) in the interval 0 <= t <= 4, increase by 0.05

Answer 1

[Ameer Hamza]

Since 't' is a vector, use element-wise operators: https://www.mathworks.com/help/matlab/matlab_prog/array-vs-matrix-operations.html. Replace / with ./ and * with .*

thank you

Answer 2

[Andrei Bobrov]

t = 0:0.05:4;
y = t.^2./ (t+1) + 3*exp(-4*t).*cos(5*t) - 2*exp(-3*t)./sin(2*t);
