C --*** SQZTPV *** (TPLOT) Compress curves for whole time steps

C --
|
|
C --SQZTPV compresses the values for TPLOT curves so that only the values
|
|
C --for whole time steps are in the curve. Curves of history variables
|
|
C --only are left intact.
|
|
C --
|
|
C --Parameters:
|
|
C -- NPTIMS - IN - the number of selected time steps
|
|
C -- IPTIMS - IN - the selected time steps
|
|
C -- WHOTIM - IN - true iff whole (versus history) time step
|
|
C -- NPTS - OUT - the number of points on each curve
|
|
C -- PLTVAL - IN/OUT - the plot data;
|
|
C -- PLTVAL(x,NTPVAR+1) holds the times if TIMPLT
|
|
C -- PLTVAL(x,NTPVAR+2) holds the compressed times if TIMPLT and needed
