I have a matrix as follows for example where the first column is X coordinate, second column is the Y coordinate and third column is the Z coordinate. How can i turn this matrix into a point cloud with pcwrite and pcshow? It has to be in a point cloud format.
[1 8 9; 2 3 4; 9 8 6]

xyz = [1 8 9; 2 3 4; 9 8 6];
ptCloud = pointCloud(xyz)
pcshow(ptCloud,'MarkerSize',1000)

Try
plot3(x, y, z);
or
scatter3(x, y, z);
or, if you have a surface rather than a cloud
surf(x, y, z);

I never heard of it but I guess Hiroki has and it seems there is a function to put it into that class. Then you can export it somehow, like using save() to put it into a .mat file. What program are you exporting it for? What program will use this data that you exported? Does that program know how to read in .mat files? If not, what formats does that program know about?

I think that pcshow function will woks
pcshow([1 8 9; 2 3 4; 9 8 6])
By the way, you can convert xyz matrix into point cloud format by pointCloud function
ptCloud = pointCloud(xyzPoints)
in this case,
ptCloud = pointCloud([1 8 9; 2 3 4; 9 8 6])
