For example, an array of data might be a financial statement, and therefore, it might be necessary to sum the 3rd through 5th rows and place the result in the 6th row. This is a legitimate array operation that Matlab supports. The matrix is fundamental to Matlab and we have provided a ...
for is used when the number of loops is determined, while is mostly used when the number of loops is uncertain. 下面举一个例子,使用for语句和while语句分别求1到100的和。 Here's an example that uses the for statement and the while statement to sum from 1 to 100, respectively. for语句代码...

For example, the introduction of a class named A on the MATLAB path could change the meaning of an assignment statement like A.B = C inside a .m code file. In other languages, classes rarely use static data, except as private data within the class or as public constants. In MATLAB, ...
For example, the following statement allocates an m-by-1 floating-point mpsArray initialized to 0: myData = mpsCreateDoubleMatrix(m, 1, mpsREAL); C/C++ programmers should note that data in a MATLAB array is in column-major order. (For an illustration, see Data Storage.) Use the mps...
To mimic the behavior of a do...while loop, set the initial condition of while to true and place the conditional expression inside the loop. For example, implement the do...while loop above by using a MATLAB while loop. while true statements if ~expression break end end Extended...
Turn on echoing of statements for the functionbuggy, and then run the function. MATLAB displays each statement inbuggyin the Command Window as they execute, then displays the output ofbuggy. echobuggyonbuggy(1:5) function z = buggy(x) n = length(x); z = (1:n)./x; end ans = 1 ...
For example, enter this statement in the Command Window: str = sprintf('%s%s', ... '', ... 'Generate magic square'); disp(str) MATLAB displays this in the Command Window: However, the diary file, when viewed in a text editor, shows this text instead: Generate magic square Tips T...
example Examples collapse all Use if, elseif, and else for Conditional Assignment Create a matrix of 1s. nrows = 4; ncols = 6; A = ones(nrows,ncols); Loop through the matrix and assign each element a new value. Assign2on the main diagonal,-1on the adjacent diagonals, and0everywhere...
Example #1 This example performs a simple task. The basic idea is to run a switch statement and print a message based on a condition. We create a logic for matching the number and providing an output based on the number. Code: N = input('Enter a number of your choice: '); ...
