Saving a MATLAB File in Python: The n by 1 Cell Array

Saving data to MATLAB's .mat format can sometimes pose a challenge for Python users. Many run into issues when trying to save an array in a specific configuration, especially when it comes to the dimensions of the data. One common issue is trying to create an n by 1 cell array, which is especially critical for data organization and usability in MATLAB. This guide will guide you through the process of saving a cell array in that exact format using Python's SciPy library.

Understanding the Problem

In MATLAB, a cell array can hold different types of data. When working with Python's SciPy library, you might encounter difficulties when converting a standard list into a cell array in the correct shape. For example, if your initial list looks like this:

You may end up with a 1 by n configuration, rather than the desired n by 1 structure. When saved incorrectly, the data may not behave as expected when opened in MATLAB.

Solution Overview

To generate the desired n by 1 cell array, you need to create a list of lists in Python. This ensures that when the data is saved, it preserves the structure that MATLAB expects. Let’s break this solution down step-by-step.

Step-by-Step Instructions

Step 1: Import Required Libraries

First, you need to import the necessary modules from Python. Make sure you have the scipy library installed.

Step 2: Create a List of Lists

Instead of using a standard list, you will transform your labels into a list of lists. Each label will be encapsulated within its own list. This will create the desired n by 1 structure.

Step 3: Prepare Your Data Dictionary

Next, create a dictionary that maps a key to your Label data. This will be useful for saving in the .mat format.
