I have a binary 3d data of 1800 points, I have created an image using meshgrid and griddata. The points I have after now is 121 in all coordiantes. I have to increase the num,ber of points by interpolation. How to do this

Read about griddata, scatteredInteprolant.

Your motive is not clear still.... you said xx1, yy1 are the indices from M for which the value is 1 i.e zz1 is 1. Am I right? So for this, though you do inteprolation, the respective value will be 1, there is no point in doing interpolation.
Are you taking about increasing the number of points between (xx1,yy1) alone, where these points form a curve?

xx1, yy1 and zz1 are indices from M. I find x, y from meshgrid taking xx1 , yy1 as input and then use interpolation using girddata to find z. thereafter increasing the number of points between (x,y,z) alone, where these points form a curve
