I have a $80\times200$ matrix, and I want to plot its contents with the contourf command in MATLAB, as follows:\begin{align}&\text{[C,h] = contourf(mat,100);}\\&\text{set(h,'LineColor','none');}\end{align}The resulting image, as you can see, has some step-like discontinuities where the white part meets the coloured part. Is there any way to smooth this region with curve-fitting tool or other methods?
