how to join vectors of different lengths in matlab

To join vectors of different lengths in Matlab, you can use the cat function. The cat function concatenates matrices along a specified dimension. Here's an example:

main.m
% Create two vectors of different lengths
x = [1 2 3];
y = [4 5];

% Join the vectors along the first dimension
z = cat(2, x, y);

In this example, x and y are vectors of lengths 3 and 2, respectively. We use the cat function to join the vectors along the first dimension (i.e., concatenate them column-wise). The resulting vector z will be [1 2 3 4 5].

If you want to join the vectors along a different dimension, simply specify a different dimension number as the first argument to the cat function.
