i. Extended |
initial writing: 2007-05-15 |
Previously, x i. y signalled error if the rank-r cells of y do not have the same shape as the the rank-r cells of x , or if y has rank less than r , where r=:0>.(#$x)-1 is the rank of an item of x . For example:
x=: i.10 2 3 y=: i.4 5 2 4 x i. y |length error | x i.y
This has been changed to return #x for each rank-r cell. Thus:
x i. y 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10
Note that x i. y already returned #x for cells having a wrong type, a situation no less egregious than having a wrong shape.
x i. 4 2 3$'deipnosophist' 10 10 10 10
The dyads i: e. -. have also been extended similarly.
