isEqual

check for equality of symbolic scalars

Calling Sequence

t = isEqual( a, b )
t = ( a == b )

Arguments

a, b

symbolic scalar

t

boolean

Description

Returns true (%t) if symbolic scalars a and b are equal and false (%f) otherwise.

Examples

// some symbolic variables
a = %(Sym("x+5"))
b = %(Sym("5+x"))
c = %(Sym("1"))
d = %(Sym("1.0"))

// symbolic equality?
a   == b
b   == c
c   == c
2*c == 2*d
c   == d

// clean up
reset();
clear a b c d;
