在 MATLAB Online 中打开

cell(linspace(1,100,1000))

;)

linspace(1,100,1000) would contain non-integer values, which cell would not be able to use a dimension sizes to construct a 1000-dimensional cell array.

This does not create a cell array.

No. In MATLAB, numbers automatically drop leading 0's when displayed.

What is possible is to create a cell array of strings from '0000' to '1000'.

cellstr(num2str(0:1000).', '%04d')

Note: the .' is required there; without it the strings would come out wrong.

Thank you, Xiangrui Li, you are correct.

There is also the undocumented

sprintfc('%04d', 0:1000)

Also since R2016b, there has also been

compose('%04d', 0:1000)
