MATLAB has two functions, polyfit and polyval, which can quickly and easily fit a polynimial to a set of data points. A first order polynomial is the linear equation that best fits the data. A polynomial can also be used to fit the data in a quadratic sense.
How to Do Curve Fitting in MatLab: 12 Steps (with Pictures)
The same values for the parameters can also be obtained by using polyfit, a function provided by Matlab, to find the best linear fit of the data. % Matlab program for Example 5.1-1 % Least square curve fitting of ln(Ca) = ln(Cao) - kt

YAY! YAY MATLAB!! Step 3 - Lets first talk about the data we are fitting: we will define N as the number of data points to fit, and lets call the actual data we wish to fit y(i). In our case, there are 2 variables to the function we are fitting the data to (m and b), so let’s define p as this quantity (p=2).

ERIC – as you see fit ... (a vector in MATLAB). The line above shows how to fill the first two elements of that vector. ... For example, if your raster/histogram plots show that the neuron responded best to motion at 180 deg (downward motion), then your tuning curve should show the same motion direction preference.

This creates a new model file where you can define your system in terms of a block diagram. To import new blocks you need to open the SIMULINK library by typing at the MATLAB prompt (command window). Then “drag-and-drop” the desired blocks from the library and connect them (double-click-hold-and-drag creates a connection line).

The graphical output shows the plot of the semivariance as a function of the distance. Experimental results appear as symbols. The plain line gives the best fit for the model chosen. The optimal values of a, b and C are also displayed on the graph. Example r = (0:10)’; x = 1 - exp(-r); fitvario(2,[r x],2) fitvari2(2,[r x],2,0,1.5) See also
