Line color, specified as an rgb triplet, a hexadecimal color code, a color name, or a short name. The first input of ezplot command is a string describing the function. Problem with ezplot function and transcritical bifurcation. The char function converts symbolic expressions to strings, you can also use the vectorize for the same purpose but its different, vectorize adds dots before expressions like and so that operations like this t2 where t is a vector wont fail because of the size of the vector, vectorize turn the symbolic expression t2 into t. When i try your code in r2012a on osx, the two lines are dashed. The rgb triplet is a threeelement row vector whose elements specify the intensities of the red, green, and blue components of the color.
An rgb triplet is a threeelement row vector whose elements specify the intensities of the red, green, and blue components of the color. If the plot happens to concentrate the solutions over a relatively small area, then you will get a number of dashed lines close together, with the visual impression of a solid line. All you need to do to use it is to state the function you would like to plot, and it does the rest of the job. For a custom color, specify an rgb triplet or a hexadecimal color code. Defines the colors used by the plot and plot3 functions to color each line plotted. By default, ezplot plots a univariate expression or function over the range 2. If f is an equation or function of two variables, the default range for both variables is 2. If the inputs are matrices, then polarplot plots columns of rho versus columns of theta. Ezplot and plot are two commands that allow to graph function in matlab. The plot appears on the screen in blue which is the default line color.
However this seems to cause some infinite loop, as instead of plotting almost instantly as it was previously doing, it causes my computer to make a lot of noise and takes a long time, and i always end up cancelling it before it finishes. When you zoomed in, the points of the plot would be further apart and the dashed line would be more obvious. Explicitly specifying line colors when plotting a matrix. If the plot happens to concentrate the solutions over a relatively small area. Plot expression or function matlab fplot mathworks. This matlab function plots the expression funx over the default domain 2. It just isnt immediately obvious, especially in the light green color that is automatically chosen for me. Conflict between ezplot and linestyle matlab answers.
Plot a figure and then use the following matlab function. Im trying to use ezplot plot a symbolic function, and i will then use hold on to plot another picture with it though just using the plot function this time. If you do not specify a line color with plot and plot3, these functions cycle through the colororder property to obtain the color for each line plotted. Alternatively, one of the inputs can be a vector and the other a matrix as long as. What is the difference between the ezplot and plot. The graphics engine in r2015a does short line segments a bit differently to avoid this problem. The r2014a bug were seeing here had to do with the length of the individual line segments that ezplot was creating. The inputs must be vectors with equal length or matrices with equal size.
For example, the matlab syntax for a plot of the expression, x. Array multiplication, division, and exponentiation are always implied in the expression you pass to ezplot. Not recommended easytouse function plotter matlab ezplot. How to zoom a portion of graph in matlab without a crosser.946 1104 1540 29 337 1578 542 1131 430 1023 749 1349 742 644 1016 356 564 438 1300 1133 1551 1323 355 1143 313 316 278 1202 1330 561 1089 464 736 418 782 1532 1387 1057 1063 190 480 1112 1071 907 1097 900 1252
