backend: backend to use

Outputs

i: Returns the 'recent cpu usage' for the whole system.
b: backend used

This value is a double greater than 0. If the system recent cpu usage is not available, the backend returns a negative or NaN value.

function [i, b] = cpu_load(backend)
if nargin < 1
  backend = {'java', 'python', 'sys'};
else
  backend = cellstr(backend);
end

for j = 1:numel(backend)
  b = backend{j};
  switch b
    case 'java'
      i = stdlib.java.cpu_load();
    case 'python'
      if stdlib.matlabOlderThan('R2022a'), continue, end
      i = stdlib.python.cpu_load();
