Khi một chuyến bay trong tình trạng huỷ, hãng hàng không cố gắng để tìm các chuyến bay thay thế cho khách hàng của mình. Một hoạt động là một hành vi ngắt. Nó có thể chạy hoàn thành trong khi đối tượng trong tiểu bang đó,Một ma trận m-by-n có hàng từ 0 đến m1 và cột từ 0 đến n-1. Tuy nhiên, người sử dụng | A A 1 You can change c to reflect this change in A by retyping the lengthy command c . above but it is easier to hit the up arrow key until you see the command you want and then hit enter. You can clear the Command window with the clc command or with Edi t clear command window. Although all numeric computations in MATLAB are performed with about 16 decimal digits of precision the format of the displayed output can be controlled by the following commands format short format long format short e format long e format short g format long g format hex format format bank format rat fixed point 5 digits fixed point 15 digits scientific notation 5 digits scientific notation 15 digits fixed or floating-point 5 digits fixed or floating-point 15 digits hexadecimal format - and blank dollars and cents approximate ratio of small integers format short is the default. Once invoked the chosen format remains in effect until changed. These commands only modify the display not the precision of the number. The command format compact suppresses most blank lines allowing more information to be placed on the screen or page. The command format loose returns to o 2002 by CRC Press LLC the non-compact format. These two commands are independent of the other format commands. You can pause the output in the Command window with the moue on command. Type moue off to turn this feature off. Workspace window This lists variables that you have either entered or computed in your MATLAB session. There are many fundamental data types or classes in MATLAB each one a multidimensional array. The classes that we will concern ourselves with most are rectangular numerical arrays with possibly complex entries and possibly sparse. An array of this type is called a matrix. A matrix with only one row or one column is called a vector row vectors and column vectors behave differently they are more than mere onedimensional arrays . A 1-by-1 matrix is called a scalar. Arrays can be introduced into MATLAB in .
