evstr
evaluation of expressions
Calling Sequence
H=evstr(Z) [H,ierr]=evstr(Z)
Arguments
- Z
matrix of character strings
M
orlist(M,Subexp)
- M
matrix of character strings
- Subexp
vector of character strings
- H
matrix
- ierr
integer, error indicator
Description
Returns the result of the evaluation of the matrix of character
strings M
. Each element of the matrix must define a
valid Scilab expression.
If the evaluation of M
expression leads to an
error, the single return value version, H = evstr(M)
,
raises the error as usual. The two return values version,
[H,ierr] = evstr(M)
, on the other hand, produces no
error, but returns the error number in ierr
.
If Z
is a list, Subexp
is a
vector of character strings, that defines sub_expressions which are
evaluated before evaluating M
. These sub_expressions
must be referred to as %(k)
in M
,
where k
is the sub-expression's index in
Subexp
.
evstr('a = 1') is not valid (use execstr
instead).
Nan, NaN will be interpreted as %nan.
Inf will be interpreted as %inf.
Examples
a = 1; b = 2; Z = ['a', 'b'] ; evstr(Z) a = 1; b = 2; Z = list(['%(1)','%(1)-%(2)'],['a+1','b+1']); evstr(Z) evstr('NaN'), evstr('Inf')
