HARSFEN0602
Perform an indexed iteration in a program.
Syntax:
for k=N1:N2:N3
…
end
or
for k=N1:N2
…
end
where N1, N2, and N3 are numbers or simple expressions.
The syntax:
for k=N1:N2:N3
…
end
iterates k from N1 to N3 with a step of N2.
The syntax:
for k=N1:N2
…
end
iterates k from N1 to N2 with a step of 1.
Notes:
1. If the iteration step is zero, the program is aborted with the error code
INFINITE_LOOP.
2. If N1, or N2, or N3 are variables, they are evaluated once before the iteration
begins. If the variable changes within the "for" loop, the iteration process will not be
affected.
3. Iteration variable k must be declared as a variable.
Example:
…. Start user program or function
float ra[20]; Float array declaration
int ia[20]; Integer array declaration
int k; Variable declaration
…
for k=1:10 Start of iteration loop
ia[k]=100; Update the first ten elements of the integer
array
ra[k]=55.55; Update the first ten elements of the real array
…
end End of iteration loop
