Matlab to Python: String Uppercase and Size Conversion

This example demonstrates how to convert a snippet of Matlab code to its Python equivalent. In Matlab, the code:

h = upper(h);
[m,n]=size(h);

converts the string 'h' to uppercase and stores its dimensions in variables 'm' and 'n'. Here's the Python equivalent:

h = h.upper()
m, n = h.shape

In Python, the upper() method is used for converting strings to uppercase, while the shape attribute provides the dimensions of the string (or any array) as a tuple.
