MATLAB is for matrix calcs. Matrix indices start at 1, fight me. Given a matrix X of m x n size, you write

Matlab has many issues, amongst other accessibility (which can be remedied by piracy), closed-software, but as a program designed to do computational matrix manipulation, starting at index 1 is literally correct. This is how you learn matrix indices in intro linear algebra. How is it make sense then you use a software to assist computation and start indexing at 0, while you write the equations and indices on a piece of paper you start at 1. CS majors go home.

Starting at 0 makes sense in low-level languages like C because it's not really an index but a memory offset. Higher level languages like SQL or MatLab correctly start at 1 because they abstract memory management away. Other languages without manual memory management, such as JavaScript or Python, are incorrectly starting their arrays at 0.
