Getting the following error:
Error using matlab.graphics.chart.primitive.Surface/set
Value must be a vector or 2D array of numeric type
Error in matlab.graphics.chart.internal.ctorHelper (line 8)
    set(obj, pvpairs{:});
Error in matlab.graphics.chart.primitive.Surface
Error in surf (line 150)
hh = matlab.graphics.chart.primitive.Surface(allargs{:});
Error in surfc (line 53)
    hs = surf(cax, args{:});
Error in (line 68)
    surfc(phi_12,phi_13,X); colorbar;
can anyone please help me fixing this error?

Best Answer

You need to use isosurface() instead of surfc()
