Description

This block computes an output vector y with y[i]= u[i]^a where a is the real scalar given by the parameter to the power of and u the input. The input and output port sizes are determined by the compiler according to the connected blocks port sizes.

Dialog box

• to the power of

  A real scalar, the exponent value.
