HELP: Index in position 2 is invalid. Array indices must be positive integers or logical values.

I got this error in my code file: "Index in position 2 is invalid. Array indices must be positive integers or logical values."

It refers to these lines:

Index in position 2 is invalid. Array indices must be positive integers or logical values.

Error in straighten>getInterpolatedValue (line 65)

I(1,1) = IM(x(1),y(1))*(1-x(3))*(1-y(3));

Error in straighten (line 50)

IM2(ct,ct2) = getInterpolatedValue(IM,xStart,yStart);

Error in test7 (line 68)

IM2 = straighten(IM,[x;y]',450);

I've tried checking if I entered the equation wrong or if I have to save certain values as integers but nothing seems to work.I have attached 2 files of my code. What should I do to fix this error? Any advice would be greatly appreciated.

Your fcn file straighten.m that contains one crucial mistake, i.e.:

The command in it on line 10 has a conflict:

IM2(:,:,ct)=straighten(IM(:,:,ct),pts,width); that must be fixed.

Note that the same function within the same function file can't called.
