Index exceeds the number of array elements (0).

I keep getting this error:

Index exceeds the number of array elements (0).

Error in S5_HoughTransform (line 58)

X = [lines(i).point1(1);lines(i).point2(1)];

You are trying to index a variable that has no elements.

a = []

a =

     []

a(1)

Index exceeds the number of array elements. Index must not exceed 0.

thank you very much for your answer.

i think my problem is in:

lines=houghlines(g,theta,rho,peaks);

for some reason it returns the value of 0.

Could be. It may be because no edges were found in your image, so g is empty.
