How do i step from a bigger number to a smaller number ?

I want to create an array with two numbers like this;
Xprime = x1 : 0.01 : x2
but when i make x1 > x2 i get an empty array.
Is there a solution to this ?

In general, if you don't know what x1 and x2 are, and which one will be bigger, you can do
x1 = 3
x2 = 2
inc = 0.01;
xPrime = x1 : sign(x2-x1) * inc : x2
If you know how many steps you want between the two, you can use the linspace() function instead:
numSteps = 10;
xPrime = linspace(x1, x2, numSteps)

If you want to create a decrement array, you should use
Xprime = x1:-0.01:x2;

x = 2:-0.01:1
x = 1×101
2.0000 1.9900 1.9800 1.9700 1.9600 1.9500 1.9400 1.9300 1.9200 1.9100 1.9000 1.8900 1.8800 1.8700 1.8600 1.8500 1.8400 1.8300 1.8200 1.8100 1.8000 1.7900 1.7800 1.7700 1.7600 1.7500 1.7400 1.7300 1.7200 1.7100
