What is the difference between a[] and a{}?

(a) a[] is for empty cell array while a{} is for empty linear array

(b) a[] is for empty linear array while a{} is for empty cell array

(c) No difference

(d) a[] is an empty row vector while a{} is an empty column vector

This question was posed to me during an interview for a job.

I would like to ask this question from Vectors and Matrices in section MATLAB Basics of MATLAB

The correct answer is (b) a[] is for empty linear array while a{} is for empty cell array

Explanation: To initialise a cell array, named a, we use the syntax ‘a{}’. If we need to initialise a linear array, named a, we use the syntax ‘a[]’. This is pre-defined in MATLAB.
