how to plot a function of 3 variables ?

My function is dependent on (x,y,z) ,the mesh grid of x,y,z was obtained from sph2cart function of a meshgrid of r(0.14 to 0.28),theta(0 to 360),phi(90 to -90). I wanted to plot this function in x,y,z plane with tthe function acting as varying intensity.when i used slice function it gave me "Error using griddedInterpolant The grid was created from grid vectors that were not strictly monotonic increasing."

surf(x, y, z, f, 'edgecolor', 'none')

It gave me an error on matrix dimensions.
