evstr - evaluation of expressions

Calling Sequence

H=evstr(Z)

[H,ierr]=evstr(Z)

Parameters

• Z : matrix of character strings M or list(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).

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)
