Please debug this code showing error as

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

and how to conver function from nnmin to MIN()

Answer 1

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
