I understand that you are getting this error 'Matrix dimensions must agree'.
This is because of matrix dimensions of the matrices being used in your code do not match.Specifically, when you are using pcolor function then the size of inputs to the function must be of the same size.
Therefore, to resolve this error, you need to ensure that the matrices you are using with the 'pcolor' function have the same dimensions.
- ‘lat_ncep’ has dimensions as 1 * 360
- ‘lon_ncep’ has dimensions as 1 * 180
pcolor(lat_ncep,lon_ncep,var1) function have three inputs ‘lat_ncep’,’lon_ncep’ and ‘var1’ . So They all must be of the same dimensions.
