how to add all parentheses in symbolic logic expression

Hello,

I am working on matlab 2020b and I have a relatively long logic phrase, an example would be:

a & b & c & (d & e & f | g & h & j) & (k | p)

The computation is done first on the & and later on the |, if I understood correctly.

This logic phrase is obtained after running :

simplify(evalin(symengine, someLogicPhrase))

My issue is that this phrase is used by some users and I would like to add parentheses when the logic phrases between | are long. I would change the previous one to something like this:

a & b & c & ( (d & e & f) | (g & h & j)) & (k | p)

Where there are new parentheses that will make it more user-friendly in my case.

Is there any easy way to do it using the symbolic toolbox? or any other.

Thank you in advance,

If I am understanding this correct, you want to modify a symbolic expression?

When you have long logic phrase, you may use newlines to improve readability. Place operators at the end of a line, rather than at the beginning of a line.

You can use extra newlines when it helps with readability, e.g.

if (c > 30 &&  // is cost per unit must be high?
   d > 40) {  // and distance travelled high?

   // code
}

Generally, Use of parentheses is an indicator that standard operator precedence rules are not in use, for example, "a = b * (c + d)" indicates to the reader that standard operator precedence is not in use.
