This program calculate approximated value of x at a certain value of t using linear interpolation.

F = lininterp1f(X,Y,XI,Ydefault) returns the value of the 1-D function Y at the points XI using linear interpolation. Length(F)=length(XI). The vector X specifies the coordinates of the underlying interval. Ydefault is returned for values of XI outside the coordinates in X. For lininterp1f to work properly:

Interpolation is a technique for adding new data points within a range of a set of known data points. You can use interpolation to fill-in missing data, smooth existing data, make predictions, and more.

In Matlab we can do this task by simply setting up   Here, we will mainly discuss one-dimensional interpolation or linear interpolation syntax: aq=interp1(x, a, xq): This returns the interpolated values of the function (  In MATLAB, you should use the function interp1. From the help: vq = interp1(x,v, xq) returns interpolated values of a 1-D function at specific query points using  Sep 20, 2016 Write a function in Matlab to perform linear interpolation. The function call should look like yval=linear_interp(x,y,xval);. where xval can be a  z = 0:0.25:50;. One way to find the y-values of z is piecewise linear interpolation. z_y = interp1(x,y,z,  In this section, you will see how to write recursive functions in Matlab. It can be shown that any function written in a recursive manner can be rewritten using loops;  'nearest', Nearest neighbor interpolation.

Hardware Verification (System VERILOG, Matlab) 3. They can be implemented by using linear interpolation or zero-padding followed by low-pass IIR or 

Description. yi = interp1q (x,Y,xi) returns the value of the 1-D function Y at the points of column vector xi using linear interpolation.

At that point, the linear interpolation is little more than an add or two, a divide, and a multiply.

Fortunately, Matlab has also several built-in function to interpolate values with different methods (' interp1 ', ' interp2 ', ' interp3 ', and ' interpn '). ' interp1 ' is called one dimensional interpolation because vector y depends on a single variable vector x. The calling syntax is ynew = interp1 (x, y, xnew, method)
