example

C = uminus([A](#btykb4h-A)) is an alternative way to execute -A, but is rarely used. It enables operator overloading for classes.

Examples

collapse all

Create a 2-by-2 matrix, A.

Negate the elements of A.

Input Arguments

collapse all

Input array, specified as a scalar, vector, matrix, or multidimensional array. If A has an integer data type, then it cannot be complex.

Complex Number Support: Yes

Extended Capabilities

expand all

Theuminus function fully supports tall arrays. For more information, see Tall Arrays.

The uminus function fully supports GPU arrays. To run the function on a GPU, specify the input data as a gpuArray (Parallel Computing Toolbox). For more information, see Run MATLAB Functions on a GPU (Parallel Computing Toolbox).
