For computation of area the value of y1,y2 and y3 are coming from three different same dimension matrix and so I want to compute area of using this code for same matrix dimension as y1, y2 and y3?
x=[7.8 8.25 8.55]; y=[0.96 0.99 0.94]; p=polyfit(x,y,2); t=linspace(x(1),x(3)); yhat=polyval(p,t); a1=trapz(t,yhat);
How can I improve code for all 3*3 matrix of given y1,y2 and y3, result will be area a1 of 3*3 matrix.
