在 MATLAB Online 中打开

f = inline('x');
w= whos('f')
w = 
          name: 'f'
          size: [1 1]
         bytes: 1130
         class: 'inline'
        global: 0
        sparse: 0
       complex: 0
       nesting: [1x1 struct]
    persistent: 0
f = @(x) x.^2;
w= whos('f')
w = 
          name: 'f'
          size: [1 1]
         bytes: 32
         class: 'function_handle'
