Description
Ordinarily, each Scilab function, has its
own local variables and can "read" all variables created in the base
workspace or by the calling functions. The global
keyword allow to make
variables read/write across functions. Any assignment to that variable,
in any function, is available to all the other functions declaring
it global
.
If the global variable does not exist the first time you issue
the global
statement, it will be initialized to the empty matrix.
Examples
//first: calling environnment and a function share a variable global a a=1 deff('y=f1(x)','global a,a=x^2,y=a^2') f1(2) a //second: three functions share variables deff('initdata()','global A C ;A=10,C=30') deff('letsgo()','global A C ;disp(A) ;C=70') deff('letsgo1()','global C ;disp(C)') initdata() letsgo() letsgo1()
