Multidimensional Arrays

This chapter discusses multidimensional arrays, MATLAB arrays with more than two dimensions. Multidimensional arrays can be numeric, character, cell, or structure arrays. These arrays are broadly useful--for example, in the representation of multivariate data, or multiple pages of two-dimensional data.

This chapter covers the following topics:

• Multidimensional Arrays
• Computing with Multidimensional Arrays
• Organizing Data in Multidimensional Arrays
• Multidimensional Cell Arrays
• Multidimensional Structure Arrays

MATLAB provides a number of functions that directly support multidimensional arrays. You can extend this support by creating M-files that work with your data architecture.

Function	Description
cat	Concatenate arrays.
ipermute	Inverse permute array dimensions.
ndgrid	Generate arrays for N-D functions and interpolation.
ndims	Number of array dimensions.
permute	Permute array dimensions.
shiftdim	Shift dimensions.
squeeze	Remove singleton dimensions.
