Hi all
I'm new to MATLAB and am having trouble with a certain function, called score. I've looked at this for a while now and can't see where I am going wrong?!
The function scores the similarities of two matrices,
1 for a match
-1 for a non match
the code:
function s = Score(x,y,d)
% Score matirx for x and y in {1,2,3,4}
% Mismatch penalty = d
s = ((x==1)'*(y==1)+(x==2)'*(y==2)+(x==3)'*(y==3)...
+(x==4)'*(y==4))*(1+d) - d;
input:
x = ceil(4*rand(1,5))
y = ceil(4*rand(1,7))
[0 y; x' Score(x,y,1)]
..and that error...
? Error using ==> _times_transpose
Function '*' is not defined for values of class 'logical'.
Error in ==> C:\MATLAB6p5p1\work\Score.m
On line 6 ==> s = ((x==1)'*(y==1)+(x==2)'*(y==2)+(x==3)'*(y==3)...
.. i;m not sure what it is?! I'm sure its something dumb.
Can you suggest a learning resource, my curernt approach is to go through online tutorials.
Thanks for your time
