How do i export to blender?

I have this code:

y = rgb2gray(imresize(imread('DSC_0009.jpg'),.2)); 
z = 255.0 - 1.0 * double(y);
 z = z ./5 ;
 z2 = imfilter(z, fspecial('average', 15));
 z2(z2 > 35) = 35;
 z2(z2 < 30) = 0;
 surface(z2);
 shading interp;
 axis ij;
 axis tight;

Can i ask help to make the output file of this be converted into a format that blender can read? i am trying to make a 3d model.

please help me.

In a duplicate question you asked about using saveobjmesh.m

[X,Y] = ndgrid(1:size(y,1), 1:size(y,2));
saveobjmesh(X, Y, z2);

I'm afraid this does not run on recent Matlab versions (tried on 2022b).
