defining and plotting a function in MATLAB

Hello,

I am trying to plot this function:

p = @(theta) p0_CSF*sin(theta)*((1-exp(TR/T1_CSF))/(1-exp(TR/T1_CSF))*(TE/T2_CSF) (where I have defined all variables above it)

plot(theta,p)

and I get this error:

Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.

Could you please explain the error and how to fix it?

Thank you!

Your missing a closing parenthesis!

p = @(theta) p0_CSF*sin(theta)*((1-exp(TR/T1_CSF)))/(1-exp(TR/T1_CSF))*(TE/T2_CSF)
% I guessed it should be                    there:^
plot(theta,p(theta))
