b={{{3 ;4}; {1}; {5}; {2}};{{1;2}; {2}; {2}; {4}}}
b =
{4x1 cell}
{4x1 cell}
and the output i required is
b =
{4x1 double}
{4x1 double}
i have used this but it gives me error
bb=cell2mat(b)

This is not what you asked for.. You said you have a 1x3 cell array, and you didn't mention that your cell are cells of cells with different sizes

Also, you can't get
{4x1 double}
For your case it's
{5x1 double}

d= cellfun(@(y) cell2mat(cat(1,y{:})),b,'un',0)
