create a cell array of numbers

hi

i need to create a cell array with numbers from 0000-1000

notice that numbers must be in a 4-digit format

how can i do this?

thanks

Do you want a cell, which contains strings, or a matrix of type CHAR wither line breaks as separators?

[Tobias Müller]

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.

Answer 1

[Azzi Abdelmalek]

   str = sprintf('%04d\n',0:1000)

[Walter Roberson]

This does not create a cell array.

Answer 2

[Walter Roberson]

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.

[noa]

"??? Error using ==> cellstr

Too many input arguments."

[Walter Roberson]

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

[Xiangrui Li]

It should be

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

[Walter Roberson]

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)
