Numeric to Symbolic Conversion. This topic shows how Symbolic Math Toolbox™ converts numbers into symbolic form. For an overview of symbolic and numeric arithmetic, see Choose Symbolic or Numeric Arithmetic.. To convert numeric input to symbolic form, use the sym command. By default, sym returns a rational approximation of a numeric expression. The purpose of sym(A,'d') is to convert a numeric values and arrays into symbolic form. You have two options. 1. Use something like sym(A,'d') to convert your numeric values to inexact symbolic decimal form before they are incorporated into your symbolic expressions. This . double(s) converts the symbolic value s to double precision. Converting symbolic values to double precision is useful when a MATLAB ® function does not accept symbolic values. For differences between symbolic and double-precision numbers, see Choose Symbolic or Numeric Arithmetic.
