**equation How to find coefficients in MATLAB using**

I have a graph which represents the heat flux around circumferential angle of a cylinder. i need a polynimial equation (heat flux = a +( b* theta) + (c*(theta)^2 ) + d*(theta)^3 + e *(theta)^4) for the conditions like 0 to 45, 45 to 180 and 180 to 360 degree . can any one explain me how to make fourth order polynomial equation for the specfic... Matlab has two functions, polyfit and polyval, which can quickly and easily fit a set of data points with a polynomial. Thus a straight line is a first degree polynomial equation. The reason the degree is equal to one is that the "x" in the equation is raised to the power of one (it has an exponent

so I created the polynomial by p=polyfit(X,Y,7) and I was asked to find the real solutions of this so I used r=roots(p) and all i get are imaginary numbers.... p = poly(r), where r is a vector, returns the coefficients of the polynomial whose roots are the elements of r. example p = poly( A ) , where A is an n -by- n matrix, returns the n+1 coefficients of the characteristic polynomial of the matrix, det ( Î»I â€“ A ).

As radarhead wrote in his comment, you forgot the coefficient of zero degree (p(4) here). Assuming x and y are vectors of same length n, polyfit(x,y,n-1) will return a vector containing the coefficients of the interpolating polynomial (of degree n-1) in descending order.... p = poly(r), where r is a vector, returns the coefficients of the polynomial whose roots are the elements of r. example p = poly( A ) , where A is an n -by- n matrix, returns the n+1 coefficients of the characteristic polynomial of the matrix, det ( Î»I â€“ A ).

- Use the fzero function to find the roots of a polynomial in a specific interval. Among other uses, this method is suitable if you plot the polynomial and want to know the value of a particular root.
- It is a general nonlinear equation, not a polynomial. Calling it that does not make it so, even though it looks vaguely like one.
