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.
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
