Subject: ??? Index exceeds matrix dimensions.

I have the following code (part of a larger program) in `matlab`:    while(k<n)    C.(sprintf('Cnew')) = C.(sprintf('C%d',k));    d1 = equalize_dimension(a.F, C.(sprintf('Cnew')));    distance_new = distance(d1.x, d1.y);    k = k + 1;    endIf you want to substitute values since I have included part of the program, this would be as follows:    C.(sprintf('Cnew')):78And, for `a.F` it is as follows:78    82    84    8080    84    86    8282    87    88    8582    87    89    86For the `equalize_dimension(x,y)` function, it is as follows:    function n = equalize_dimension (x,y)            [r1 c1] = size(x);            [r2 c2] = size(y);                        if r1<r2            e= r2-r1;            for i=1:e            x(r1+1,1)=0;            r1 = r1 + 1;            end            [r1 c1] = size(x);            n.x =x;            n.y = y;            end                if r1>r2            e = r1-r2;            for i=1:e            y(r2+1,1)=0;            r2 = r2 + 1;            end            [r2 c2] = size(y);            n.x = x;            n.y = y;            end                if c1<c2            e= c2-c1;            for i=1:e            x(1,c1+1)=0;            c1 = c1 + 1;            end            [r1 c1] = size(x);            n.x = x;            n.y = y;            end                if c1>c2            e = c1-c2;            for i=1:e            y(1,c2+1)=0;            c2 = c2 + 1;            end            [r2 c2] = size(y);            n.x = x;            n.y = y;            end                        if r1==r2 && c1==c2            n.x =  x;            n.y = y;            endAnd, for the `distance(x,y)` function, it is as follows:    function m = distance(x,y)    [r c] = size(x);    for i=1:r         for j=1:c         summation = (sum(sum(pdist2(x,y))));         end    end         m=summation;    endWhen I run the program, I get the following error:    ??? Index exceeds matrix dimensions.        Error in ==> fs at 36    distance_new = distance(d1.x, d1.y);Why is that?Thanks.
