Thank you for your help in advance. Suppose I have two strings namely, Source and Target,
Source: abcde
Target: hello
Is there a function for me to calculate the distance between the characters (using alphabetical series) in Source and Target?
Example answer: [7][3][9][8][10]
Explanation: [8-1][5-2][12-3][12-4][15-5]

Explanation: in MATLAB character arrays are arrays just like numeric arrays, so many mathematical operations can be performed on them. Read about character arrays:

If you want the edit distance, then use this algorithm:
