If I have an array a of arrays, in many languages they may have different size. Is there a word for an array of arrays where all the arrays have the same length?
Edit: An array of arrays may have the following form:
[ [ 1, 2, 3 ] [ 1, 2, 3, 4 ] [ 1, 2 ] ]
But in order to convert this to a matrix you would have to assume some default value or trim the arrays. The following array of arrays is possible to convert into a matrix without any asumptions or trimming as all arrays have same length.
[ [ 1, 2, 3, 4 ] [ 1, 2, 3, 4 ] [ 1, 2, 3, 4 ] ]
Is there some name or classifier for a matrix of this kind?
