Sander Temme <sander@temme.net>. 2. “Apache is a general webserver, which is designed to be correct first, and fast second. Even so, its performance is quite satisfactory. Most sites have less than 10Mbits of outgoing bandwidth, which Apache can fill using only a low end Pentium-based webserver.”. Kalyx McDonald. Mississippi . Valley State University. Mentor.

A script is a file that contains many lines of code.. You can edit the code using . Matlab’s. Editor.. Once you have the code set up the way you want it, you can have Matlab run the entire script from the Command Window by typing in the name of the script.. Booleans. Booleans are a class of variable that have values of 0 or 1.. 0 = false. 1 = true. George Boole. (1815-1864). Booleans. Using the code on the right, we can set the value of two variables (a and b) and then ask Matlab if they are equal to each other using “==“. 2. What is MATLAB?. MATLAB, which stands for “MATrix LABoratory” is a high-performance language for technical computing. . It integrates computation, visualization, and programming in an easy-to-use environment where problems and solutions are expressed in familiar mathematical notation.. (log(. t), log. (. x)).

To assign a single value to a variable, simply type the variable name, the = sign, and the value:. >> a = 4. a =. 4. Note that variable names must start with a letter, though they can contain letters, numbers, and the underscore (_) symbol.
