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.
How to load mat files on matlab.
Load workspace variables from disk.
To determine the current folder at the matlab command prompt enter pwd.
The default file name is untitled mat if you specify a file name without path information simulink loads the file in the current folder or on the matlab path.

Can you say me how to write this in the code of the function.

When you are a beginner it seems like a cunning and fast way to store information but actually it is really bad practice to name your variables dynamically.
When working with these large.
If you do not specify filename the load function searches for a file named matlab mat.

And just like a box can contain something so can a structure hold your data.
When you wish to access your data you first need to get it out of the structure just like you would get something out of the box before you can use it.
I ve recently started to learn matlab.
If filename has no extension that is no text after a period load looks for a file named filename mat if filename has an extension other than mat the load function treats.
Thanks for your time.
A load 1 mat imshow a this is the shortest possible way and 1 is the name of the image.
A structure is like a box.
This is a brief post which explains how to load these files using python the most popular language for machine learning today.
I ve used it my throughout my engineering degree and chances are you will come across mat files for datasets released by the universities.
You can save and load parts of variables directly in mat files without loading them into memory using the matfile function.
Name of file specified as a character vector or string scalar.
Matlab is also not intended for this kind of variable naming.
I need to load a mat file a matrix of 57x9 as input of my function.
If you continue to include data in the variable names then you will find yourself fighting many more of these battles against matlab.
