Using an Array as an input

I am trying to compute the energy produced by a solar panel in a 24 hour period using a personally mde function computeEnergy.

function [Energy Total_Energy] = computeEnergy(Pan, t)

Energy = exp(-(((t-12)^2)/(1.5*sqrt(2*pi))));

Total_Energy = Pan*Energy;

end

While using t = [1:24] and Pan = 1 as inputs, I get the errors :

Error using ^ (line 51)

Incorrect dimensions for raising a matrix to a power. Check that the matrix is square and the power is a

scalar. To perform elementwise matrix powers, use '.^'.

Error in computeEnergy (line 8)

Energy = exp(-(((t-12)^2)/(1.5*sqrt(2*pi))));

I don't know where I need to incorporate new code to fix the problem.

The error message actually tells you exactly what to do. Use element-wise operator .^ instead of the matrix operator ^

Energy = exp(-(((t-12).^2)/(1.5*sqrt(2*pi))));
