Unexpected MATLAB expression.

i try to make equation but when i run have problem Unexpected MATLAB expression.

a=(T) 247.8./((T-273)+68.12963))

anyone can help me

MATLAB does not have implicit multiplication between adjacent values or variables. You need to write the multiplication explicitly:

a = T .* 247.8./((T-273)+68.12963)
      ^^ You need this!

I also fixed the unmatched parentheses.

thank you, why i try to write a=(T) not work sometime i have write like this?

[Walter Roberson]

a = @(T) 247.8./((T-273)+68.12963))

would create a as a handle to an anonymous function that took T as an argument.

If you just did

a=(T);

then that should work, but if you do

a=(T) 247.8./((T-273)+68.12963))

then there is no operator between the T) and the 247 and that causes a problem. Computer programming is not like writing or textbooks, where you can just leave out the multiplication symbol. If you want to multiply two things, like T and 2, or T and A, then you must put either a matrix multiplication operator, T*A, or an element-by-element operator T.*A.

done, thank you very much Walter
