You cant have the string 5 be the index into an array. Then you remove rows from data8, whose size therefore decreases 9 rows, 8 rows. But x is not defined, did you mean to use the variable a as input. We do not know that it has at least as many rows as p has or perhaps one fewer.

Ive not done this specifically and its not convenient at the moment to fire up matlab to test but im thinking needs to pass the range as the vector 10. Gdx file contains 7 columns and 386 rows, gld file contains 7 columns and 765 rows, but if im taking a sample of 250 out of both this should not be a problem.

I was going around mathworks forums and i found this tip i wanted to share with you guys. Certainly naive, but i do not understand why this compiles. Also, as said, an easy way to ensure that your loop does not go above the number of elements in a vector is by asking the vector how many elements it actually has rather than using a variable which may or may not be up to date. Why do i get the error index exceeds matrix dimensions.
Developed by mathworks, matlab allows matrix manipulations, plotting of functions.
