additional command is included to check whether exactly one argument is entered.
Comment lines enhanced.
1.0.3.2

help permmoves is enhanced.
1.0.3.0

comments lines are rearranged
for loop is replaced with "mfbin = (sigma ~= 1:L);"
output is received only as numeric array (second output argument is removed)
help is enhanced with an example. preallocating mfbin in removed, as mfbin is not created dynamically.
1.0.2.2

small letter 'l' is replaced with capital letter 'L', preallocating the cell array is done by using cell(1,L), Error message is changed from 'Input a valid permutation' to 'Enter a valid permuation'
1.0.2.1

Addition: If the input argument is not a valid permutation, function will display an error message
1.0.2.0

Most of the suggestion received through comments were incorporated. Function's output arguments are modified to receive the numerical array output as first (default) output and the second output argument explains the first argument in detail.
