Introduction to matlab programming data structures indexing cell arrays i one important concept. Given observations of a random process, their histogram is an estimator of the random processs pdf probability. When you save this file, matlab automatically generates two files. Some of the code area are grayed out, because this view does not allow for editing directly, it can only be changed via interactive ways offered by app designer. Working through the examples will give you a feel for the way that matlab operates. Like the exponential distribution, the generalized pareto distribution is often used to. This tutorial gives you aggressively a gentle introduction of matlab programming language. It is an interactive program for numerical computation and data visualization, which along with its programming capabilities provides a very useful tool for almost all areas of science and engineering.
