Syntax
Description
B = single(A)
converts the matrix A
to single-precision, returning that value in B
. A
can be any numeric object (such as a double
). If A
is already single-precision, single
has no effect. Single-precision quantities require less storage than double-precision quantities, but have less precision and a smaller range.
The single
class is primarily meant to be used to store single-precision values. Hence most operations that manipulate arrays without changing their elements are defined. Examples are reshape
, size
, the relational operators, subscripted assignment and subscripted reference. No math operations are defined for single
objects.
You can define your own methods for the single
class by placing the appropriately named method in an @single
directory within a directory on your path.
Examples
a = magic(4); b = single(a); whos Name Size Bytes Class a 4x4 128 double array b 4x4 64 single array
