Assign CPU variable with memory checking (kind R4P, rank 3). Variable is returned not allocated if right hand side is not allocated.

Type | Intent | Optional | Attributes | Name | ||
---|---|---|---|---|---|---|
real(kind=R4P), | intent(inout), | allocatable | :: | lhs(:,:,:) |
Left hand side of assignement. |
|
real(kind=R4P), | intent(in), | allocatable | :: | rhs(:,:,:) |
Right hand side of assignement. |
|
character(len=*), | intent(in), | optional | :: | msg |
Message to be printed in verbose mode. |
|
logical, | intent(in), | optional | :: | verbose |
Flag to activate verbose mode. |
