You have a "clear" so there cannot be anything in your workspace after that.
Then you define R1=rp-r1; without having assigned anything to r1. Is r1 a function? Likewise for r2 and r3 at the point of assignment? You redefine r2 and r3 after that point, which gets confusing.

Rb=(((1/2).1)-rp);
You do not have an operator between the (1/2) and the following .1

This is my coding in mfile, it shows this error: Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To construct matrices, use brackets
instead of parentheses. Where should I amend

that is not matlab code. You need readfis https://www.mathworks.com/help/fuzzy/readfis.html

function plotPatientHealth[Pulse Rate in BPM, temperatue] = returnPatientHealth(returnPatientHealth)
That line is not valid MATLAB syntax.
When you have a function line, if you have an =, then the left side of the = can be a single MATLAB identifier, or it can be a comma-separated list of identifiers in [] .
You have an identifier followed by something in [] . You cannot have anything indexed on the left side of a = for a function statement. Also, Pulse Rate in BPM is not a valid MATLAB identifier name.
function plotPatientHealth(Pulse Rate in BPM, temperatue)
The names there must be valid MATLAB identifier names. Pulse Rate in BPM is not a valid MATLAB identifier.
