Interpolate set of values. Griddata -> scatteredInterpolant

Hi, I am quite new to MatLab. I need your help with one of my problems. I have a big matrix M(100*10) and N(100*100). I have to interpolate the data in it. currently griddata function was used for it which take much time and a warning to use scatteredInterpolant. So I tried the scatteredInterpolant for it. Unfortunately I am getting errors( such as Error using scatteredInterpolant Input data point values must be specified in column-vector format) as I couldn't understand how it is working.

for w = 1:100
[x,y,z]=griddata(M(:,8),M(:,9),N(w,:),...   
         min(M(:,8)):0.1:max(M(:,8)),...
        (min(M(:,9)):0.1:max(M(:,9)))');

Please help me with the same. I need the z(intensity) values in the later script

use interp2..

Thank you. I tried it. But I get the error the grid vectors must contain unique points matlab

Can you attach image of surf(M,N) ?

Hello. The matrixes M & N are not of same size. to be specific Matrix M(100*10) is the matrix with details of 100 measurement points(each row) and matrix N(10*100) is the values of the 100 measurement points(columns) at 10 time stamps. These dimensions(100*10) are just examples. In reality its much bigger :)
