Can anyone explain why I'm getting this error?

I am trying to code for a 2 variable function u(y,t).

My variables are as follows:

omega=3pi/2, gamma=1, uo=5, alpha= (-sqrt(omega./2*gamma)) beta= omega*t

I keep getting "error using _* _ " on my funtion of

u(y,t)=uo*exp(alpha*y)*sin(beta+alpha*y).

I'm very new to Matlab, so I'm not sure what I'm coding incorrectly. Any advice is greatly appreciated!

Here is the error code in its entirety:

"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 operate on each element of the matrix

individually, use TIMES (.*) for elementwise

multiplication."

Answer 1

[VBBV]

omega=3*pi/2

There is missing multiplication operator

[VBBV]

u(y,t)=uo*exp(alpha*y).*sin(beta+alpha*y)

[VBBV]

Use element wise .* multiplication if y is a vector
