How to interpolate X from Y in MATLAB?
It’s best to use one of the interpolation functions to do what you want. To interpolate ‘x2’ from ‘y2’, reverse the usual order of the arguments (x,y) and use (y,x) instead, as I did here. The graph shows your original data as a green line and the interpolated points as blue stars. Please log in to answer this question.

What is an example of linear interpolation in MATLAB?
MATLAB interpolation examples. Find the following examples that explain the concept of linear interpolation in Matlab: Example #1. To define the sample values of x and a to find the interpolated values: x = 0:pi/2:4*pi; a = cos(x); xq = 0:pi/12:4*pi; aq = interp1(x,a,xq); plot(x,a,’o’,xq,aq,’:.’); title(‘Default Interpolation’);
How to plot the interpolated values without defining the specified points?
To plot the interpolated values without defining the specified points: There are several types of interpolation methods in Matlab. Linear Interpolation Method – This is the default interpolation method used. Helps to find the interpolated values at the query point that is based on the values of the grid points in each defined dimension.
How to interpolate X2 from y2 in Excel?
To interpolate ‘x2’ from ‘y2’, reverse the usual order of the arguments (x,y) and use (y,x) instead, as I did here. The graph shows your original data as a green line and the interpolated points as blue stars. Thank you! Is there a way to make sure the interpolated data is on the line of best fit? My pleasure!
What are the different types of interpolation in MATLAB?
The function you are looking for is interp1. You can use it in two ways, if you want linear interpolation you can simply use: If you want a different type of interpolation put the type you want as the 4th parameter: Available interpolation methods are: nearest, linear, spline, pchip and cubic.
How to find the x value corresponds to the y value?
– MATLAB Answers – MATLAB Central Finding Does the X value correspond to a particular Y value? I have an array, X= [5 6 9 8 4] Y= [8 7 2 1 9] If I plot this and I need to get the position of the X value corresponds to Y=1, does that mean in which row is the X the value 8 is located? the answer must be the 4th position.
