Hi gretl users,
I am looking for a simple way to determine the column for which scalar B
is, let's say, larger or equal to the entry A[i] and store this
information in scalar C. If B is never greater than any entry in A[i], C
is zero.
Reading out each entry via a loop is possible, but I am wondering
whether there is a short-cut to this.
C = 0
A = seq(4,1)
B = 3
# check at which entry A[i] the value of B >= A[i]
Maybe somebody a nice suggestion :-)

This is my experiment:
CC=(A .<= B)?1:0
CC
CC (1 x 4)
0 1 1 1
But that wont give you the indexes.
Good luck

Hi there,
this is an ordinary if then or else loop in Fortran and Basic, but instead
of storing the found result in "C"
I'suggest creating a (4x1) matrix columm vector and store the "found values
in the column vector at each "i" location
and I suspect it is the same in Gretl but I confess to being a novice at
Gretl sorry to say right now
Best wishes to all,
Hope these few commnts are of small help
Good luck

Thanks Helio,
I actually just forgot the "." for the element-wise iteration over A.
The solution is given by summing up the resulting C which gives the
position A[i] for which B>=A[i]. If the sum(C)+1 is greater cols(A), B
is never greater than any A[i]:
<hansl>
A = seq(4,1)
matrix B = 3
C = (B.>=A)?0:1
matrix pos = 0
pos = sum(C)+1
pos
pos<\hansl>
@ Richard: This is my first idea, but I was looking for a simpler way
avoiding any use of loops here.

You are welcome,
but I'd be pretty sure a true grtl wizard will pop by shortly o hlp you out
I atill think the be way o hnl our problem i by using a volumn vector ond
let the program do the "bubble Sort" looping work
fingers crossed for you
Seems to me rom ht ou write that you r mkin things oo hard for yourselfl
WHy Sum things ?
Set up 2 vectors of size to hold all the numbers say A[4] nd B[4]
iNitialize B[i]=0
THen loop for i =1 to 4
If a[i].> b[i] then b[i]= a[i]
b[i] will hold your result all sorted for you
if you get me ?
Richard Hudson
Kind Regards

You say "the" column: does that mean A is a row vector and at most one
element of A is <= B? If so:
scalar i = iminr(A)
scalar C = A[i] <= B ? i : 0
If more than one element of A can satisfy the condition and you want the
index of the first such element:
scalar i = imaxr(A .<= B)
scalar C = A[i] <= B ? i : 0
