hello!
i am currently working on wavelet analysis.i need to normalize a
wavelet.i have seen in a book that the method is to divide the
wavelet by dividing the square root of the total wavelet variance.

the problem is when i do the matlab code of this it is showing the
following: >> var(1,psi_daughter)
Warning: Complex part of array subscript is ignored.
Warning: Subscript indices must be integer values.
??? Index into matrix is negative or zero. See release notes on
changes to
logical indices.

can anybody tell me how to get rid of this?
thanx in advance.

are you sure of var(1,psi_daughter)? It should be
var(psi_daughter,1). see help var

Rename the variable var in your code. MATLAB is trying to index into that
variable using the subscripts 1 and your psi_daughter array. Since your
psi_daughter array contains complex values, it throws the first warning.
Since psi_daughter contains noninteger values, it throws the second warning.
Since the real part of your psi_daughter array contains at least one
negative value or zero, it throws the error.

Because of the existence of this variable, MATLAB is not calling the VAR
function with inputs 1 and psi_daughter, as you expect. Removing or
renaming this variable will cause MATLAB to call the function.
