 real
 real part

 Calling Sequence real(M)

Parameters

 M - array or expression

Description

 • The real(M) function computes the element-wise real part of M.  The result, R, is formed as R[i,j] = real(M[i,j]).

Examples

 > $\mathrm{with}\left(\mathrm{MTM}\right):$
 > $M≔\mathrm{Matrix}\left(2,3,'\mathrm{fill}'=-3+I\right):$
 > $\mathrm{real}\left(M\right)$
