Hello,

I don't know if this has been discussed before but...

What algorithms are running behind these functions? There are occasions in which they will deliver different results for the same equation and start guess.

This can be verified with any equation with a certain number of zeros inside a particular interval where the zeros are close to each other.

Edit: fsolve will behave similarly. The only one able to give the expected results was SOLVE, with capital letters. By 'expected result' I mean the nearest to the guess.

Thanks.

Marcio
