When i run this Matlab code from the internet, I have errors in the code which says:

Brace indexing is not supported for variables of this type.

Error in Letter_detection (line 8) cor=corr2(NewTemplates{1,n},snap);

Error in Plate_detection (line 37) letter=Letter_detection(Iprops(i).Image); % Reading the letter corresponding the binary image 'N'.

note: I do have the appropriate files from alpha
