If there are many values, then a can be declared in an array. The input ‘x’ is a vector that contains every sample point, a has the defined values and xq contains the coordinates.
aq=interp1(x, a, xq): This returns the interpolated values of the function (one-dimensional) with the help of the linear interpolation method. Here, we will mainly discuss one-dimensional interpolation or linear interpolation syntax: Various functions are associated with interpolation techniques. It is used to find the missing data in the data set, smoothen the given data set or predict the outcome of the given data set. In Matlab, interpolation is the procedure of including new points within a defined range or a given set of points. Working of Interpolation in Matlab with Syntax and Examples: I'm really not even sure what to suspect.Īny help, tips, comments, or criticisms are appreciated.Hadoop, Data Science, Statistics & others Or the placement of the interpolation formula. I feel like it has something to do with my notation. The plot for the given data is working fine. mfile as of right now: function mu_val=linear_interp(T,mu,i) Also include on the plot the results from using a polynomial that goes through all of the data using 1K spacing, and the original data.Īnd this is what I've got down on my. Using this function, create a plot of mu(T) with a spacing of 1K. Where xval can be a scalar or a vector, and yval has the interpolated values at locations corresponding to xval. The function call should look like yval=linear_interp(x,y,xval) 
Write a function in Matlab to perform linear interpolation. Here's the problem as it was given on the assignment: I graphed the given data, that was pretty straightforward, but the interpolation itself is tripping me up.
We were provided a table of data for temperatures in K and viscosity of air at those temperatures. So I'm working on an assignment that calls for linear interpolation, but we aren't allowed to use the interp1 command.
