Please debug this code showing error as

Error: File: GA1.m Line: 77 Column: 1

At least one END is missing: the statement may begin here.

and how to conver function from nnmin to MIN()

Answer 1

[Joost]

It look like you would like to reproduce from this article:

http://www.ijaamm.com/uploads/2/1/4/8/21481830/v2n3p27.pdf

The nnminr function computes the minimum for each row (is explained in the article).

It can be achieved in Matlab using:

min(A, [], 2)

where A is the matrix you want the minimum of each row for.

So this line:

minc=nnminr(x);

then would become

minc = min(x, [], 2);

Regarding the missing end statement, it should be added after line 106

count = 0;
end

Thank you so much it really work but the result which i got is not matching i think there is a error in evaluation process

[Joost]

Around line 22 you miss a '.

minc = min(x, [], 2);

should be:

minc = min(x', [], 2);

or, which is essentially the same as:

minc = min(x, [], 1);

and which is also the same as:

minc = min(x);

At two positions in the code you find things like:

[yc yr] = find(x == 10);

These should also get an extra ' :

[yc yr] = find(x' == 10);

Got it Thank you so much....
