◆ des_coef_phi()

const char * device = 0x0,
int newgraph = 3,
int nxpage = 1,
int nypage = 1 )

Plots the coefficients of the spectral expansion in $\phi'$ of a Valeur .

This routine performs a logarithmic plot of the coefficients of the $\phi'$ expansion of the coefficient which is in front of a given $\theta'$ basis function (index j ) and a given $\xi$ basis function (index i ) in the general spectral expansion of a field. The plotted quantities are the logarithm of the absolute value of the coefficients, using solid lines (resp. dashed lines) for positive coefficients (resp. negative coefficients).

Parameters
uu[input] Valeur the $\xi$ coefficients of which are to be plotted
l[input] index of the domain
j[input] index of the considered basis function in $\theta'$
i[input] index of the considered basis function in $\xi$
pzero[input] positive number under which (in absolute value) a coefficient will be considered as zero (default value = 1.e-14)
nomy[input] y legend of the figure (default value = 0x0,
corresponds to no y legend)
title[input] title of the figure (default value = 0x0, corresponds to no title)
device[input] PGPLOT device (default value = 0x0)
newgraph[input] controls the opening/closing of the graphic device:
0 : does nothing (the device must be already opened)
1 : opens the device but does not close it at the end
2 : closes the device at the end but does not open it at the beginning
3 (default value) : opens and closes the device
nxpage[input] number of graphs in the horizontal direction of the display window (meaningfull only if newgraph = 1 or 3) (default value = 1)
nypage[input] number of graphs in the vertical direction of the display window (meaningfull only if newgraph = 1 or 3) (default value = 1)
