evstr

Arguments

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).

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')
