converting a 35x28 matrix into 35x35 matrix
显示 更早的评论
I have one set of data with 1x1.25 degrees resolution and another set with 1x1 degree resolution. On extracting data over India the first set of data is giving a 35x28 matrix while the second set is giving 35x35 matrix. Now to catenate the two data along 3rd dimension the matrix size needs to be same. How can I change the 35x28 matrix into 35x35 matrix?

Hi,
You can pad your first set of data as follows:
data1Mod = [data1 zeros(35,7)];
This will give a 35x35 matrix which you can then concatenate. This assumes you don't mind padding with zeros. You can obviously pad with anything else.

I should have added that you need to be more clear on how you want to handle the "missing" data. I have just shown how to pad it. You might want to extrapolate, copy etc. Phil

You should probably be using interp2() or imresize() to extrapolate one of the two data sets to be the same size as the other; then you can concatenate them along the third dimension.
