Good evening. Could someone help me?

How to show the result of a substitution in Matlab other than in division form? Show decimal form number?

'res' is a variable that holds a polynomial expression

'subs was used to replace the expression x with 1

'valor0' receives the result of the substitution

the words to be replaced are:

(1993864719626009*x 5)/144115188075855872 + (4984661799068339*x 4)/144115188075855872 + (61595834957061*x 3)/36028797018963968 + (23355*x 2)/46837 + (46847*x)/46837 + 1

CODE LINE:

valor0=subs(res,x,1);
disp(valora0)

COMMAND WINDOW RESULT IS:

573384793757928688891/210935095747151921152

  • Your question does not pass the [mcve] test. Your code gives an error.

  • As you have some questions that have been left outstanding, it is worth a brief explanation. It is good you do the [tour] on the website. When writing a question, whenever possible put everything you need to run the code (if possible simplify, see [mcve]), not just the part that is in trouble.

If you want to display this output in decimals I think the following functions can help. Try to use double(variavel), or the function vpa(a,b), where is a input variable and b is the number of decimal places you want to display.
