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.
Free diver breaks world record by holding his breath underwater 22:22 minutes. A German 'free diver' has apparently entered the Guinness World Records by holding his breath under water for more than 20 minutes. Tom Sietas, 35, competed with former record holder, Brazilian Ricardo Bahia, to set the new record by not inhaling for 22:22 minutes.
In 2014, the Curvier beaked whale broke the record for the mammal that could hold its breath underwater the longest.The longest dive was recorded at 2 hours and 17 minutes. It was previously thought that elephant seals could hold their breath the longest, with a record of 2 hours. Although they arenât mammals, sea turtles hold the record for the animal that can hold its breath the longest underwater. When resting, sea turtles can stay underwater for days. On average, sea turtles can hold their breath for 4 â 7 hours. Green sea turtles can hold their breath for as long as five hours, whereas Loggerhead sea turtles hold the record for the longest documented dive, remaining underwater for longer than 10 hours. How do humans compare? Compared to these amazing aquatic mammals, humans still have a long way to go.
