Release notes summary of new features, bug fixes, upgrade issues, etc. Display the matched area by using the drawrectangle function. Normal distribution the lognormal distribution is closely related to the normal distribution. Sometimes the algorithm converges to a solution of lower rank than k, which may indicate that the result is not optimal w and h are normalized so that the rows of h have unit length.
This example is not meant to be an ideal analysis of the fisher iris data, in fact, using the petal measurements instead of, or in addition to, the sepal measurements may lead to better classification.
