#Plot surface vector 2d windows#

: row vector or matrix of complex numbers (complex frequency response).Д«ode plot, i.e magnitude and phase of the frequency response of sl. : row vector or matrix ( phases (in degree)) : row vector or matrix ( magnitudes (in Db)).

: row vector or matrix (frequencies (in Hz) ) : vector of character strings (captions). : syslin list (SISO or SIMO linear system) in continuous or To plot the grid of iso-gain and iso-phase of y/(1+y) use chart(). (see calfrq for theД¬omments is a vector of character strings (captions).Дb,phi are the matrices of modulus (in Db) and phases (in degrees). Step is the ( logarithmic ) discretization step. The frequencies are given by the bounds fmin,fmax (in Hz) or by a row-vector In case of multi-output the outputs are plotted with different Sl can be a continuous-time or discrete-time SIMO system (see syslin ). : row vectors or matrices (complex frequency response)Д«lack's diagram (Nichols'chart) for a linear system sl. : row vectors or matrices (modulus, phase) If a color defined in c is already present in current colormapДў.6 black Black's diagram (Nichols chart)Д«lack( sl, ) ( R is red component, G is green component,Д« is blue component).

Index of the colors defined in c in the new color tableДЄddcolor, adds new colors given in the c argument toД¬urrent colormap. : matrix with 3 column, RGB color definition Sfgrayplot X, fgrayplot X, grayplot X, fec XДў.5 addcolor add new colors to current colormap The function is plotted assuming that it is linear on a set triangles of z gives the value of the function on the grid x.*.y. Like grayplot but the function fec is used to smooth the Sgrayplot X, fgrayplot X, grayplot X, fec XДў.4 Sgrayplot 2D plot of a surface using gray levels f is evaluated on the grid x.*.y and the result is plotted assuming that f is linear on the triangles built on the x.*.y grid. Like fgrayplot but the function fec is used to smooth the Д®nter the command Matplot() to see a demo. The color associated to a(i,j) is usedДo draw a small square of length 1 and with center at location (x=j,y=(n2-i+1)). The entries of matrix int(A) are used as colormap entries in Xlfont : to load a new family of fonts from the X-Window ManagerД¬olormap : to get information on using colorsДЄddcolor : to add new colors in the colormapДў.2 Matplot 2D plot of a matrix using colors Xget : to get information on the current graphic context Xclea : clears a rectangular zone inside the current graphic window. Xselect : raises the current graphic window.
