Creating vectors from columns of a matrix

I have a matrix containing indices of elements for example:
A = [55 59; 242 270]
How can I create a matrix that has rows starting at the first element and ending at the second element of each row of A, i.e. :
B = [55 56 57 58 59; 242 243 ... 269 270]

You can not obtain the output you want in terms of numeric data type due to size mismatch for vertical concatenation. You can obtain the output in terms of cell arrays -
A = [55 59; 242 270]
out = arrayfun(@(x) A(x,1):A(x,2), 1:size(A,1), 'UniformOutput', false)'
