sort function that arrange by abs in matlab

In order to sort a list of numbers in MATLAB by absolute value, you can use the abs function to first take the absolute value of each number in the list, and then use the sort function to sort the list based on these absolute values. Here is an example:

main.m
% create a list of numbers
nums = [-3,-2,-1,0,1,2,3];

% take the absolute value of each number
abs_nums = abs(nums);

% sort the list by absolute value
sorted_abs_nums = sort(abs_nums);

% use the sorted list of absolute values to rearrange the original list
sorted_nums = nums(abs_nums == sorted_abs_nums);

In the code above, we create a list of numbers nums, and then use the abs function to create a new list abs_nums that contains the absolute value of each number in nums. We then use the sort function to sort the list of absolute values abs_nums. Finally, we use the sorted list of absolute values sorted_abs_nums to rearrange the original list nums and obtain the sorted list of numbers sorted_nums.
