I have measured the thd of the analog signal using the fft function of a tektronix scope and i know the correct thd to be less than 1%. For example, if x is a matrix, then prctilex,50,1 2 returns the 50th percentile of all the elements of x because every element of a matrix is contained in the array slice defined by dimensions 1 and 2.
If you use imdistline with an axes that contains an image object, and do not specify a drag constraint function, then you can drag the line outside the extent of the image.

However, when i try to do this using matlab i am not getting the correct results and i expect this is because i am doing it incorrectly. If y is a matrix, then it returns one errorbar object per column in y. I would like to select multiple points in my figure using the data cursor, and export the coordinates of these points to the matlab workspace. For example, i would like to select index 2,4 from 1,2,5,7,9 at first, and then select index 1,2. Frequency table matlab tabulate mathworks switzerland. Convert the resulting cell array tbl to a table array t.
The resulting matrix differs from the matrix returned by the matlab orth function because these functions use different versions of the gramschmidt orthogonalization algorithm.
