how to set a vector of array

[J.Zhang]

Hi Frank,

How are you? I have a problem in the design of input of data from the interpreter.

I am planning to input a set of data from the OpenSees interpreter, but the number of these "double values" could vary from a few to hundreds. If I use only "double" in the constructor, I must creat hundreds of constructors. So I am thinking using a vector of array in the constructor. But I can not find vector in the Tcl and even array is very different with in the C++. For example

set a {...} # {...} means a set of double type.
pattern Plain 1 Linear {
eleLoad -ele 1 -type -beamUniform $a 0. 0.;
}

What is you advice? thanks a lot

Jian

there is no vector in tcl .. the closest thing is the list.

You mean TCL script?
Try
set A ""
lappend A 4
lappend A 5
...
Then A is similar to a Vector.
When you use A, you should need foreach.
foreach b $A {
...$b..
}

It's work for me. I am facing this problem in C++ from several day but After implementing this method. linguan118, I think you have a good knowledge of this kind of language fundamental.
