Error minimization by optimizing the parameter value using fminunc

function obj = objFunction(q)

data=readtable('solu6_deleted few rows VALUE-Mat1');

A=table2array(data);

size(A)

TF1 = A(:,32)<=0.0001;

A(TF1,:) = [];

size(A)

TF2 = A(:,2)<=0.0001;

A(TF2,:) = [];

size(A)

yex=A(:,33);

x1=A(:,1);

x2=A(:,2);

f1=A(:,4);

f2=A(:,5);

T=A(:,3);

size(T)

yp=@prediction;

obj=norm(yex(':') - yp(':')).^2 ;

---------------------------------------------------

function yp = prediction(q,f1,f2,x1,x2,T)

% Unknown parameter

Q1=q(1);

Q2=q(2);

Q3=q(3);

yp=f1.*log(x1)+f2.*log(x2)+(Q1+Q2.*(f1-f2)+Q3.*(f1-f2).^2).*f1.*f2.*T./298;

what is the wrong with this code ..can anyone please help me ,if any additional info required i will share.

Basically i want to minimize the obj value by optimizing the Q1,Q2,Q3 value using fminunc.

please help me i am new to this software.
