clear an array

Hi, I want to clear the array v[] before going to the next iteration of 'j'. i.e. after the stmt arr(i,j)=min_val; /*Code begins here*/

arr=zeros(4,4);

pat='32131313';

m=8;

for i=1:4

    for j=1:4
        s=1;
        for k=1:m-1
            if str2num(pat(k))==i && str2num(pat(k+1))==j
            val(s)=m-k+1;
            s=s+1;
            end
        end
        if str2num(pat(m))==i
            val(s)=1;
            s=s+1;
        elseif str2num(pat(1))==j
            val(s)=m+1;
            s=s+1;
        else
            val(s)=m+2;
            s=s+1;
        end
        min_val=min(val);
        arr(i,j)=min_val;

    end
end

I dont see an array v[] to clear in your code. Did you mean to refer to val[]? If so, why not just add 'clear val;' on the line following 'arr(i,j)=min_val;'?

Answer 1

[Walter Roberson]

Instead of clearing val after the loop, initialize it before the loop

val = [];

[Muntazim Abbas Hashmi]

I agree

Answer 2

I got the answer

clear val;
