The appeared answer above the command window includes the coefficients of the obtained curve equation.
To use these vectors inside the polyfit() command, the number of elements of vectors must be the same.Īs you see above, we just typed the vectors inside the polyfit() command and we assigned the polyfit() command to variable ‘x’ to see the answer in the command window.
We did this by defining vector ‘a’ and vector ‘b’ as you see above. In Matlab®, you can input the two different data sets that depend on each other as vectors. To make the curve fitting, you need to define the variables and data.
To understand how to make curve fitting in Matlab® with polyfit() command, take a look at the example below that done in Matlab® command window.

How To Use ‘polyfit()’ Command In Matlab®? Here, we explain how to do curve fitting in Matlab® with vert basic examples below. Matlab® provides a bunch of curve fitting commands to make curve fitting from given or defined data. To see the characteristics of a bunch of data, curve fitting can be very useful. In general, data are obtained from the system separately.
And also in engineering and data analysis, curve fitting can be a very important tool. Curve fitting is a very fundamental thing in numerical analysis.
