Character vectors and strings in the first argument can only specify a variable or number. To evaluate character vectors and strings representing symbolic expressions, use 'str2sym'.出错 sym>tomupad (第 1608 行)S = convertChar(x);出错 sym (第 400 行)S.s = tomupad(x);出错 freexyn67 ...
Convert numeric values to symbolic numbers or expressions. Usesymon subexpressions instead of the entire expression for better accuracy. Usingsymon entire expressions is inaccurate because MATLAB® first converts the expression to a floating-point number, which loses accuracy.symcannot always recover thi...
MATLAB Online에서 열기 Hi, how can I change format of sym number? For example: a=sym(2.34353453465464); b=sym(4.6546455789879324352); formatshort c=a*b Format short doesn't work. Thanks 댓글 수: 1 Sean de Wolski2012년 3월 1일 ...

MATLAB treats the number as a double-precision number, but those elements of a numeric vector or matrix do not support replacement with a symbolic variable, function or expression as these elements cannot be converted to double-precision numbers. The functions Sym() and syms() share similar func...
