How do I expand out an array with dimension '<82794x1 cell>' in which each cell has different dimension like;
[1x12] double
[1x18] double
[1x6] double
[1x14] double
[1x6] double
[1x10] double
[1x6] double
[1x8] double.....and so

@SUSHMA MB: please run this command and tell us exactly what it displays (C is the name of your cell array):

The shown data looks like they are a cell already and not a "nested cells". Please post the type and the dimensions of the wanted output. e.g. "{1 x N} cell containing [1 x M] vectors".

Let A be your cell array. Try cell2mat(A)
A{1} = rand(1,10) ;
A{2} = rand(1,11) ;
A{3} = rand(1,7) ;
iwant = cell2mat(A)'

I have tried cell2mat. Got the following error:
Error using cat Dimensions of matrices being concatenated are not consistent.

Have you tried the code which I have given? Are you sure that your 82794x1 cell array have all row vectors?
