topic Hi everybody, in Intel® Fortran Compiler

Vector updating with implied DO does not work

Hi,

Tentatively I tried to update the second and third component in a integer vector with dimensions a(100,1,1):

a(5,1:1,1:1)=[2,3]

but the compiler discover that the two vectors had different shapes. How should this vector update be written?

Best regards

The left-hand side is a

The left-hand side is a single element of the array a, whereas the right-hand side is an array with two elements. The compiler is quite right here. I do not quite understand which elements of the array a you mean, but this should work:

a(2:3,1:1,1:1) = [2,3]

Use: a(2:3,1,1) = [2,3] !

Use: a(2:3,1,1) = [2,3] ! Where array a has dimension (100,1,1)

Hi everybody,

Hi everybody,

Thanks for your answers that made me think twice. It is embarassing to confess that I should define a as a vector a(100,2). Then

a(5,1:2)=[2,3] works fine!

Sorry to have taken your time! Vector usage apparently is not basic to everybody.

Best regards
