Create a table from vectors with different rows and fill missing

I have a number of vectors for several dates with different lenghts

• 01/06/2022: 478 rows
• 02/06/2022: 531 rows
• 03/06/2022: 502 rows
• ...

I would like to add them to one array in order to plot them afterwards.

For this, they need to be the same rows.

I was thinking to create an array with set rows A = 0:500 and for example add the first 500 values.

The vectors with less would be filled with 'Nan' and the vectors with more would be cut short.

How could I do this in a loop?

Here's a minor example that you can expand yourself

a = ones(400, 1);
b = ones(450, 1);
c = ones(500, 1);

vecDim = max([numel(a), numel(b), numel(c)])
a(end + 1 : vecDim, :) = nan;
