'SPTool is the data management tool central to all of the Signal'
'Processing GUI Tools.'
' '
'Using SPTool you can:'
' o Load a new Session.'
' o Import a signal, filter, or spectrum.'
' o Save Sessions.'
' o Activate the Signal Browser, Filter Viewer or Designer, or the'
'   Spectrum Viewer.'
' o Duplicate or clear a signal, filter, or spectrum.'
' o Change the name of any of these objects.'
' o Change the Sampling Frequency of signals and filters.'
' o Use the Window menu to change the current figure to any open'
'figure.'
' '
'For help on a specific control, choose the Context Sensitive menu'
'item off the Help menu.  The mouse pointer becomes an arrow with a'
'question mark symbol.  You can then click on anything in the SPTool,'
'including selecting menu items, to find out what it is and how to use'
'it.'

' '

'name "mtlb.mat" and hit enter.  Click on mtlb in the File Contents'
'list, and the arrow left of the Data field.  Click on Fs in the File'
'Contents list and the arrow left of the Sampling Freq. field.  Then'
'click the "OK" button.  You have successfully imported a signal named'
'"sig1" into the SPTool.  From there, click the "View" button under'
'Signals to look at this signal in the Signal Browser.'
' '
'By clicking "Create" under Spectra you can look at the frequency'
'content of the signal in the Spectrum Viewer.  Once the Spectrum'
'Viewer is open, hit the "Apply" button to compute the spectrum.'
