Undefined operator '*' for input arguments of type 'cell'

I am getting this error-"Undefined operator '*' for input arguments of type 'cell'".
T1=T(i,1);
u1=u(i,1);
Rn1=Rn(i,1);
RH1=RH(i,1);
e=0.61078*exp(17.269*{T1}/(237.3+{T1}));
d=e*(17.269/(237.3+{T1}))*(1-({T1}/(237.3+{T1})));
y=0.665-3*96.7;
G=0.5*Rn1;
ET=(0.408*(d(T1))*(Rn1-G(Rn1))+y*(900/({T1}+273))*u1*e(T1)*(1-RH1))/(d(T1)+y*(1+0.34*{u1}));

You are using curly brackets ‘{}’ here and in later assignments:
e=0.61078*exp(17.269*{T1}/(237.3+{T1}));
They define a cell, and since cells can contain anything — including character variables — arithmetic operators are not defined for them. You have to remove numeric data from cell arrays to use them in numeric calculations.
Since we can assume ‘T1’ is numeric, the solution is simply to remove the curly brackets:
e = 0.61078*exp(17.269*T1/(237.3+T1));
Unless matrix ‘T’ has previously been defined as a cell array (we can’t tell from the code you posted), that should work.
