MATLAB Answers. Copy. To comment a single or two lines of code, we can use the % character . How to get the 3rd column in an array by using 1st and 2nd column values as index in Matlab; Get list of property names and values for a MATLAB plot; Confusion in figuring out the relation between actual frequency values and FFT plot indexes in MATLAB; Retrieving X and Y values from Matlab Plot; How do I make the colorbar of my image plot in . offers. So in that case, I'd just use the x and y which are already available, and if the x is in the x array that you plotted, you can do this: in your x array, then you can use interp1() to get the interpolated/estimated y value for that x. i am so sorry for complexity the problem is that i plotted a figure of x , y then i want the program automatically uses the y value (any value) when its x value used (it is used in a loop) thanks alot for ur care.
