Creating an Array of X Values for Plotting a Function

[airelemental135]

I want to create a plot of a given function for all x values between negative infinite to negative R (for some given R value). How do I create an array for x so that my plot will include all the x values?

You can't plot on a range [itex](-\infty,-R)[/itex] since Matlab won't accept Inf or NaN as valid points in the domain of a plot.

Of course, you can overcome this simply by compactifying the domain of your function to a finite domain, and then plotting the rescaled function over the new domain.

To create an array of x values for plotting a function, you can use a built-in function in your programming language, such as linspace in MATLAB or numpy.linspace in Python. This function allows you to specify the start and end points of the array, as well as the number of values you want in between. In this case, you would set the start point to negative infinity and the end point to negative R, and choose a suitable number of points to include in the array. This will ensure that your plot includes all the x values you need. Additionally, you can also manually create an array of x values by using a for loop or list comprehension in your code.
