# how to repeat a graph in matlab

5. Thus, you won't really be able to represent a repeating decimal to infinite precision. Tags plotting; See Also. If the objects already exist then you will need to use their handles to set their values- This is one reaons why it is highly recommended to always obtain and use all graphics objects handles explicitly, and never relying on the current axes or figure being the one that you want to access. I'm not sure how you'd detect what the color was if you didn't save the handle to the colored line you plotted, but maybe there is a way by using findobj() and seeing if you can get the color of any line object as a property. %Amp = sqrt(2*Gd*delta_n); %%%from Eq. Typical … It has three parts if statement, else statement and else if statement if-else statement in Matlab. You already have a for loop in there so you clearly know how to use them. Here's the example below, Thanks for reading. So, you're limited to either 32 or 64 bits of precision. Now, let’s try to create it. In this brief article we're going to deal with it in an informal way, in order to just operate with it and create some plots in Matlab. X0=0.0044; lambda (1)=a+b.*y0+c.*lambda0+d. Then reset the hold state to off. If n is 0 or negative, the result is an empty array. Also on line 44 the figure is again calling the fig handle to plot. 1. im using plot to graph one curve but now i need to plot a second curve on a different graph so how can i open 2 graphs from one script 0 Comments. Notice that this is notthe best way to do it inMatlab, but I mention the idea because this is the fundamentalconcept, and in some programming languages it cannot be done in adfferent way. %Amp = sqrt(delta_n) * (2^k) * (10^-3) * (Omega0./Omega); Amp = sqrt(delta_n) * (2^k) * (10^-3) * (Omega0./Omega); h(iv) = sum( Amp. *lambda (i)+d. %Amp = sqrt(2*Gd*delta_n); %%%from Eq. Ternary Plots in MATLAB ®. Introduction to If-Else Statement in Matlab. Now I want to carry out the montecarlo function 300 times resulting in 300 series of 257 observations (since X has 257 observations) and then I want to plot all these series in the same graph. The figure above is clean, clear, and would be as easy to read in black-and-white as it is in color.
