They control the drawing of level curves on a 3D plot. Which function used for 3D plot in Scilab? Scilab can produce many types of 2D and 3D plots.
It can create x-y plots with the plot function, contour plots with the contour function, 3D plots with the surf function, histograms with the histplot function and many other types of plots. The most commonly used plot functions are presented in figure 19. What is a 3D contour plot?Ĭontour plots display the 3-dimensional relationship in two dimensions, with x- and y-factors (predictors) plotted on the x- and y-scales and response values represented by contours. A contour plot is like a topographical map in which x-, y-, and z-values are plotted instead of longitude, latitude, and elevation. Multiple evaluation of a function for one or two arguments of vector type : z=feval(x,f) returns the vector z defined by z(i)=f(x(i)) z=feval(x,y,f) How do I add a grid in Scilab? Matplot – 2D plot of a matrix using colors.ĭescription.
may be replaced by set(gca(),”grid”,) What is the difference between plot and plot2d in Scilab? There is no equivalent function for Matlab grid function in Scilab but it has equivalents: grid on. If you are familiar with Matlab plot syntax, you should use plot. If x and y are vectors, plot2d(x,y,) plots vector y versus vector x.
