Out of memory problem in MATLAB 2017

In general the .mat files are of 1 or 2 kb like that.

When I converted the Lat and Lon python ( numpy) files to .mat files. It goes upto around 459685kb.

So when i try to make a meshgrid of these. Matlab shows out of memory.

Is there any solution?

What dimensions are the arrays you're attempting to store?

I have two matrices now. Each of 459685 kb. I want to make a meshgrid of these. In general the .mat files are of 1kb like that..so we don't feel problem making meshgrid. But here the matrix size is huge. So that it's showing out of memory. I am unable to attach the matrix mat files as these are huge in size.

A mat file contains variables, but isn't a variable itself. So it doesn't actually have an array size. What are the dimensions of the arrays you want to process?

10848x10848

That looks like it is already a grid. Are you sure you need meshgrid on top of that?

[Joydeb Saha]

well I understood. but if the lat lon size is that high, how can i make spatial map with this

You want to plot a map with 10848^4 pixels? That will end up with this size image:

%assuming 3*8 bit RGB
sz=3*10848^4;
fprintf('%d bytes\n',sz),fprintf('%.1f TB\n',sz/(1024^4))

41545114554728448 bytes
37785.1 TB

Do you have that kind of hardware?
