how to set a domain equal to infinity in matlab

In MATLAB, you can set a domain equal to infinity using the inf keyword.

To set a single domain value equal to infinity, you can simply assign it to the variable:

main.m
x = inf;
9 chars
2 lines

If you want to create an array with all elements set to infinity, you can use the inf function:

main.m
y = ones(1, 5) * inf;
22 chars
2 lines

This will create an array y with five elements, all set to infinity.

You can also set the upper or lower bound of a numerical range to infinity using the inf keyword. For example, to create a range from 0 to infinity, you can do:

main.m
range = [0, inf];
18 chars
2 lines

Similarly, you can use -inf to set the lower bound to negative infinity.

Note that performing arithmetic operations involving infinity may produce unexpected results, so use it with caution and consider the mathematical implications.
