I AM RECIEVING THESE ERRORS

Brace indexing is not supported for variables of this type.

Error in readLetter (line 10)

sem=corr2(NewTemplates{1,n},snap); % Correlation the input image with every image in the template

for best matching.

Error in main (line 80)

letter=readLetter(Iprops(i).Image); % Reading the letter corresponding the binary image 'N'.

[Walter Roberson]

In templates, you have

letter = [A B C D and so on]
number = [one two three and so on]

On both those lines, change the [] to {}

letter = {A B C D and so on}
number = {one two three and so on}
