    I want to do 1-D interpolation such that the interpolated value for a given point will be equal to the value of the point which is closest and on the left (i.e., smalller than the given point) of the data set. In MATLAB, the IPT is a collection of functions that extends the capability of the MATLAB numeric computing environment. It provides a comprehensive set of reference-standard algorithms and workflow applications for image processing, analysis, visualisation and algorithm development.In the following exercise you will see how the singular value decomposition can be used to ``compress'' a graphical figure by representing the figure as a matrix and then using the singular value decomposition to find the closest matrix of lower rank to the original. This approach can form the basis of efficient compression methods. Exercise 3:

    This lets you find all the subscripts of a that is equal to 1 or 2. This is fine but gets cumbersome if you had to match a dozen possible numbers or if the Then you would have to use some kind of for loop with find. I just found out that there is actually an easier way using MATLAB's ismember function.Let g1 and g2 be the two closest approximations to g in the table. A look at Table B.1.1 shows that the two closest values you can find in the table are 35 C and 40 C, so in our example g1 =35 C and g2 =40 C. (The desired value is in between those two, hence the ``in'' in ``interpolation.'') ExhaustiveSearcher model objects store the training data, distance metric, and parameter values of the distance metric for an exhaustive nearest neighbor search.
