MATLAB is an abbreviation for matrix laboratory. While other programming languages mostly work with numbers one at a time, MATLABÂ® is designed to operate primarily on whole matrices and arrays. All MATLAB variables are multidimensional arrays, no matter what type of data. A matrix is a two-dimensional array often used for linear algebra. Array Creation To create an array with four elements in a single row, separate the elements with either a comma (,) or a space.
How David Blaine Held His Breath. David Blaine sits atop a sphere where he set a new world record for breath-holding, Wednesday, April 30, 2008, at 17 minutes and 4.4 seconds, during a live telecast of The Oprah Winfrey Show in Chicago.

Believe it or not, there actually have been people who have held their breath for even longer than 11 minutes, though. The Guinness Book of World Records has a special category for holding your breath underwater. Unlike the freedivers who practice static apnea, the Guinness guidelines allow contestants to breathe pure oxygen for up to 30 minutes prior to their attempt.
