However, the user can choose to " undock" any or all tools, making them appear in windows separate from the desktop. By default, most MATLAB tools are " docked" to the desktop so that they develop inside the desktop window. The desktop is a window that includes other windows display MATLAB data, plus toolbars and a " Start" button similar to that used by Windows XP. When we start MATLAB Version 7.4, a specific window known as the MATLAB desktop appears. There are three most important types of windows are:Ĭommand Windows: where commands may be enteredįigure Windows: which display plots and graphsĮdit Windows: This permits a user to create and modify MATLAB programs. When MATLAB executes, it can display various types of windows that accept commands or display data. Even scalars are acted as arrays by MATLAB: they are arrays with only one row and one column. Individual data values within an array may be accessed by including the name of the array, followed by subscripts in parentheses that identify the row and column of the particular value. An array is a collection of record values organized into rows and columns and known by a single name. Heading as a separate step from the printing of the actual table values.The structural unit of data in any MATLAB program is the array. Here is what we do:Ĭharacter of the command window of MATLAB does not allow the introduction of a String is cycled in column order through the elements of the array until allĮxample let us print the sin and cosine table labels. \n\n My table \n x … cos(x) … sin(x) \n\n ‘ ) For example I can accomplish this by writing: What happens if we don’t use the width and precision specifiers :įunction can be used to create headings to tables. Let’ s see the example below and notice also Width for x will be 5 but for b and c will be 10 places. Labels x, sin(x), and cos(x) and next to each will insert the values of x, bįloat with two decimal digits, while b and c will be displayed in scientific Output of our results we use the function fprintf ( ‘ format & label string ‘, variable listįprintf ( ‘ \n x = %5.2f sin(x) = %10.3e cos(x) = %10.3e \n\n ‘, x, b, c ) We will now see how we can write our output in our own format. Heading for one, and also we seem to be without control of the output format. Anything after % is treated as a comment. The following picture shows the necessary Ĭonstruction of the sin, cos table we mentioned earlier. First of all, is there a build in constant pi in MATLAB? Absolutely! See what the system has to say about p. Pow2 - Base 2 power and scale floating point number.įind some more about the function exp, we can type > help exp and we obtain:Ĭreate a table of sin(x) and cos(x) as x varies from zero radians to p /2 radians. Log2 - Base 2 logarithm and dissect floating point number. Of course, MATLAB has a good collection of mathematical functionsĮlementary math functions by typing help elfun at the command window ( The same is true for spreadsheets like Excel. Scientific programming very easy and pleasant. have a rich library of mathematical functions which make We saw earlier that computer languages such as C++, Visual Basic,įortran etc. Material we strongly recommend that you activate your MATLAB window and try MATLAB: Mathematical functions and formatted output
