A function identical to IMC can be achieved by keying in the linear representation of IMC , which is available by means of the verb lr=.5!:5

   lr <'IMC'
(] , ]) $ ({.&1@(1&+@]))

This representation is called a tacit definition, because the name of the argument is not mentioned in it. It is itself a function, being a composition of functions, and may be applied to an argument.

   ((] , ]) $ ({.&1@(1&+@])))2
1 0
0 1

If we create a function using this representation, we obtain the same function as IMC .

   IMT=.(] , ]) $ ({.&1@(1&+@]))
   lr<'IMT'
(] , ]) $ ({.&1@(1&+@]))
   100 time 'IMT 100'
0.005
