Incorrect dimensions for matrix multiplication.

((exp(x-4))*(x.^2)-x+1)/(2+cos(5*x))

Error using *

Incorrect dimensions for matrix multiplication.

Check that the number of columns in the first matrix

matches the number of rows in the second matrix. To

perform elementwise multiplication, use '.*'.

Error in Trapezoidal (line 18)

y=((x.^2)*exp(x-4)-x+1)/(2+cos(5*x));

Answer 1

[David Hill]

y=((x.^2).*exp(x-4)-x+1)./(2+cos(5*x));%you likely want element-wise operations .* and ./
