I have 4 variables Latitude,longitude,depth of maximum salinity and maximum salinity, I would like to create a 3D plot with these variables for a single month. These variables are located in netcdf file and I have extracted them using the netcdf package, I have tried the surface plots but it did not gain any output. The data is in 3Dimension from which I have converted into 2 Dimension by collecting data of the same month.

Do you want 3D plot or contour plot?

I need a contour plot of the variation of maximum salinity with the other 3 variables

For the contour plot, you can use

contour(lon,lat,salinity')

If you want the filled contour plot, then you can use

contourf(lon,lat,salinity')

If you want labels on the contour plot, then you can use clabel

在 MATLAB Online 中打开

You can use surf

surf(X,Y,Z,'FaceAlpha',0.5,'EdgeColor','none';)

X and Y should be the meshgrid of latitude and longitude

And in the same fashion, you can write contour3, but you will not get filled colors in contour3 (I think).
