Matlab how to use loaded mat file.

This is a brief post which explains how to load these files using python the most popular language for machine learning today. Save and load parts of variables in mat files. I have a mat file named ey1a which i need to use it in my code as one of the inputs. The simplest though least flexible procedure is to use the load command to read the entire contents of the file in a single step.

When working with these large. A load 1 mat imshow a this is the shortest possible way and 1 is the name of the image. You can save and load parts of variables directly in mat files without loading them into memory using the matfile function. Matlab is a really popular platform for scientific computing in the academia.

The file contains complex data real and imaginary i read the file like this. Name of file specified as a character vector or string scalar. The primary advantage of using the matfile function over the load or save functions is that you can process parts of very large data sets that are otherwise too large to fit in memory. The mat file object does not support evaluating function handles using the m output.
