Language data in ocr function not working

I am using matlab 2015b, I have installed ocr language data using visionSupportPackages command. when I use ocr function using language string, it shows following error

Error using ocr

Too many input arguments.

Error in temp (line 5)

txt = ocr(im2,'Language','Bengali');

The code

im = imread('21.jpg');
im = rgb2gray(im);
level = graythresh(im);
im2=im2bw(im, level);
txt = ocr(im2,'Language','Bengali');

Please show the output of

which -all ocr

I suspect you have accidentally created your own ocr.m that is taking priority.

There is another ocr in the path, problem solved when its removed, Thank you

which -all ocr
