Negate elements of fi object array
uminus(a)
uminus(a) is called for the syntax -a when a is
an object. -a negates the elements of a.
uminus does not support fi objects
of data type Boolean.
When wrap occurs, -(-1) = -1 :
fipref('NumericTypeDisplay','short', ... 'fimathDisplay','none'); format short g a = fi(-1,true,8,7,'OverflowAction','Wrap') a = -1 s8,7 -a ans = -1 s8,7 b = fi([-1-i -1-i],true,8,7,'OverflowAction','Wrap') b = -1 - 1i -1 - 1i s8,7 -b ans = -1 - 1i -1 - 1i s8,7 b' ans = -1 - 1i -1 - 1i s8,7
When saturation occurs, -(-1) = 0.99... :
c = fi(-1,true,8,7,'OverflowAction','Saturate') c = -1 s8,7 -c ans = 0.99219 s8,7 d = fi([-1-i -1-i],true,8,7,'OverflowAction','Saturate') d = -1 - 1i -1 - 1i s8,7 -d ans = 0.99219 + 0.99219i 0.99219 + 0.99219i s8,7 d' ans = -1 + 0.99219i -1 + 0.99219i s8,7
