How to compare two strings with different sizes?

14 次查看(过去 30 天)
Hi everyone,
I would like to make a matrix by comparing 2 sequences with different dimensions, if it's same character (eg: A-A), it will be traced to 1, if not it will be traced to 0.
a = 'AAGCTACGC'
b = 'ACGCAA'
However, I have trouble to make this matrix. Honestly, I am a beginner, hope you guys will help me.
Thanks a lot.

Another guess:
a = 'AAGCTACGC';
b = 'ACGCAA';
match = ( a(:)==b )
match = 9x6 logical array
1 0 0 0 1 1 1 0 0 0 1 1 0 0 1 0 0 0 0 1 0 1 0 0 0 0 0 0 0 0 1 0 0 0 1 1 0 1 0 1 0 0 0 0 1 0 0 0 0 1 0 1 0 0

A bold guess:
a = 'AAGCTACGC'
b = 'ACGCAA'
Nmin = min(numel(a), numel(b));
Nmax = max(numel(a), numel(b));
match = false(1, Nmax);
match(1:Nmin) = (a(1:Nmin) == b(1:Nmin));
