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."

omega=3*pi/2
There is missing multiplication operator
