Hello good day,
I am having issues on how to enter this equation into MATLAB.

I have it as
H/2 * cos(k*x)*cos(sigma*t)
but getting a different answer from my calculator
Thank you

Is your calculator computing the cosine of angles in degrees (which in MATLAB is the cosd function) or in radians (cos)?

If your inputs are all scalars then you can use either * or .*
If your inputs are not scalars, then you need .*
