Numbers greater than INF in matlab

  1. Jul 9, 2012 #1
    Hello all,

    I need to use numbers that are greater than 10e308 in matlab. Apparently, 52 bit matlab does not recognize them and uses INF instead of the big number. I googled for it and only got some vague answers how to deal with it (something about file exchange...).Help! please...

    thanks.

    You need the Symbolic Toolbox. If your needs are "simple" enough, then you could write an Arbitrary Precision ('BigNum') library (using, say, a vector to hold numbers on a one digit per element basis). ... or google for one, maybe this http://www.mathworks.com/matlabcentral/fileexchange/22725-variable-precision-integer-arithmetic ?
