an error to find maximum index in array in MATLAB

I want to make an array 15*15 and fill them with these code and I want to find max of a row of it. I wrote this codes in MATLAB to make an array:

a = zeros (15) - inf;

for i=1:15 
    k2=4;
    l2=1;

    k=floor((i-1)/3);
    l=mod((i-1),3);
    f=false;
    if (k==k2 && abs(l2-l)==1)
        f=true;
    end
    if(l==l2 && k2-k==1)
        f=true;
    end
    if(k2-k==1 && abs(l2-l)==1)
        f=true;
    end

    if (f)
        a(i,14)=100;
    end
end
max=200;
for i=1:15
    if(find(2,i) < max)
        max=i;
    end
end

max=0

when I wrote these codes to find maximum index in 2nd row of array this error shown:

b=a(2,:)

b =

     1  -Inf     1     1     1     1  -Inf  -Inf  -Inf  -Inf  -Inf  -Inf  -Inf  -Inf  -Inf

>> [~,index]=max(b)
??? Indexing cannot yield multiple results.

You have variable max and trying to use function max.

It's a good practice to check for existing names with exist var_name or which var_name command.

Rename your variable max in the code and remove it from the workspace with clear max.
