error in using strcmp

m getting this error in using strcmp/strcmpi:

need segmentation? YES/NO:yes Undefined function or variable 'strcpmi'.

Error in demo (line 15) if strcpmi(str, 'yes')

my code is as following:

       str=input('need segmentation? YES/NO:', 's');

        %str= input(prompt, 's');
        if strcpmi(str, 'yes')
           st=input('image contains different color object? Y/N:','s');

           % st=input(prompt,'s');

                %kmeans1();
       % else
               % trydelta();
        end

What m i doing wrong here?? Also my code also doesnt display any messages when i use prompt or sprintf even there is no error

You spelled the function name wrong (though managed to spell it correctly in your question tag!)

strcmpi

is what you need, not

strcpmi
