Matrices and arrays are the fundamental representation of information and data in MATLAB®. You can create common arrays and grids, combine existing arrays, manipulate an array's shape and content, and use indexing to access array elements. For an overview of matrix and array manipulation, watch Working with Arrays.
Creating, Concatenating, and Expanding Matrices
Create a matrix or construct one from other matrices.
Access elements of an array.
Removing Rows or Columns from a Matrix
Remove matrix rows or columns.
Reshaping and Rearranging Arrays
Change the shape or arrangement of elements in an existing array.
Create and manipulate arrays with three or more dimensions.
