bug:
-------------------------------
ismember( {'float32'}, {'adgfffffffffffffffffff'} )
error: mx_el_eq: nonconformant arguments (op1 is 0x7, op2 is 0x0)
error: evaluating binary operator `==' near line 62, column 58
error: evaluating argument list element number 1
error: evaluating assignment expression near line 62, column 16
error: evaluating if command near line 58, column 7
error: evaluating if command near line 49, column 5
error: evaluating if command near line 36, column 3
error: called from `ismember' in file

--------------------------------
fix: attached :-)
looks like you first checked to see if the items in each cell had the
same length as the search cell. but if none had the same length then
when find( [0,0,0,0...]) was called it returned an empty matrix and
which was used as an index into a variable. such as c([]) which is illegal.
