WAVPRINT Call

Wavelet Analysis

displays wavelet information

CALL WAVPRINT( decomp, request <, options> );

The WAVPRINT subroutine is used to display the information that is encoded in a wavelet decomposition.

The required inputs are

decomp

specifies a wavelet decomposition that has been computed using a call to the WAVFT subroutine.

request

specifies a scalar indicating what information is to be displayed.

You can specify different optional arguments depending on the value of request:

request=1

displays information about the wavelet family used to perform the wavelet transform. No additional arguments need to be specified.

request=2

displays the detail coefficients by level. Valid syntax is

CALL WAVPRINT( decomp, 2 <, lower <, upper>> );

where the argument

lower: is optional and specifies the lowest level to be displayed. The default value of lower is the lowest level in decomp.
upper: is optional and specifies the upper level to be displayed. The default value of upper is the highest detail level in decomp.

request=3

displays the scaling coefficients by level. Valid syntax is

CALL WAVPRINT( decomp,3 < , lower <, upper>> );

where the argument

lower: is optional and specifies the lowest level to be displayed. The default value of lower is the lowest level in decomp.
upper: is optional and specifies the upper level to be displayed. The default value of upper is the top level in decomp.

request=4

displays thresholded detail coefficients by level. Valid syntax is

CALL WAVPRINT( decomp, 4, opt <, lower <, upper>> );

where the argument

opt: is a required options vector that specifies the thresholding algorithm used. See the WAVIFT subroutine call for a description of this options vector.
lower: is optional and specifies the lowest level to be displayed. The default value of lower is the lowest level in decomp.
upper: is optional and specifies the upper level to be displayed. The default value of upper is the highest detail level in decomp.
