more than double precision please

[playmobil]

hello guys

Im integrating functions, but i need a variable with more than double precision (i need 20 sinificant digits or more). I find "format", but ..."The format function affects only how numbers are displayed, not how MATLAB computes or saves them"... help me please.

thanks

Why? Is this for a class? Why not remove the pedestal?

I haven't checked, but in Maple you can use a specified precision (I have used 30 digits for solving some eigenvalue problems). The Matlab symbolic algebra toolbox is based on Maple. So the symbolic toolbox should give you variable precision arithmetic.

Maybe....
