• Feb 20, 2015 · • MATLAB indexing starts with 1, not 0 • a(n) returns the nth element • The index argument can be a vector. In this case, each element is looked up individually, and returned as a vector of the same size as the index vector. Indexing: 40.
• The colon operator is very helpful for indexing elements of a vector. Find the first 4 elements of the vector z2 1:4 gives 1, 2, 3, 4, so you get the values of the first 4 elements of z2 .
• In MATLAB you can create a row vector using square brackets []. Elements of the vector may be separated either by one or more blanks or a comma , . Create a row vector x with elements x 1 = 1, x 2 = -2 and x 3 = 5.
• Thus, if we have a vector containing elements (2, 5, 7, 3, 8, 6, 4, 1), and we want to create an array slice from the 3rd to the 6th items, we get (7, 3, 8, 6). In programming languages that use a 0-based indexing scheme, the slice would be from index 2 to 5. Reducing the range of any index to a single value effectively eliminates that index.
• Section 5: For What Versions of MATLAB Are These Techniques Valid? The majority of these techniques should work for MATLAB 5.3 (R11) and higher, although the syntax of certain commands may have changed between the time it was released and the present. The screen shots shown in this Tech Note are taken from the Windows version of MATLAB 6.5 (R13).

• Matlab colon index

• A colon index is an expression of the form a:b or a:b:c. No rounding takes place when the indexing array is a standard array, such as [a b c] or even [a:b] or [a:b:c] . Rounding is done to the nearest integer , except that numbers between -0.5 and 0.5 are special-cased : they are rounded to 1 instead of to 0 .MATLAB notes - 1 • >> is the MATLAB command window prompt • % starting a line is a comment • There are built in functions like: sqrt and mean • When you do a calculation, result is stored in ans • x=x+1 is an assignment (not an algebraic equation) •; at end of line suppresses displaying results • up arrow will retrieve prior ... By contrast, a reference to a {1, 1} displays the contents of the data item contained in the cell. Note: The notation a(1,1) refers to the contents of the cell a(1,1) (which is a data structure), while the notation a{1,1} relates to the contents of the data structure within the cell. you don't start at index 0; and the order is in row,column format. You can also use a single index. In this case, MATLAB regards your matrix as one long column that is the concatenation of each of the original columns. So, the first four entries in b when you use a single index are: 1 5 9 13. The keyword end is used to signify the last index. Using the colon alone implies that all index values are traversed. This also indicates how multi-dimensional arrays are accessed. Or a section of an image could be abstracted using >> fc = f(top : bottom, left : right); Or the image could be subsampled using >> fs = f(1 : 2 : end, 1 : 2 : end);
• Read and Write Using Key Index. When reading from the Map, use the same keys that you have defined and associated with particular values. Writing new entries to the Map requires that you supply the values to store with a key for each one.
In MATLAB you can create a row vector using square brackets []. Elements of the vector may be separated either by one or more blanks or a comma , . Create a row vector x with elements x 1 = 1, x 2 = -2 and x 3 = 5.

• MATLAB matrix laboratory is a multi-paradigm numerical computing environment and proprietary programming language developed by MathWorks. MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages.
• Sometimes you don’t need an entire file imported into MATLAB, only certain rows and columns of it. The csvread() function provides a straightforward example of how to perform this task. To see just a range of data displayed, type CSVOutput = csvread(‘NumericData.csv’, 0, 0, [0, 0, 1, 1]) and press Enter. You see the following […]
• MATLAB executes the statement and returns the following result − ans = Columns 1 through 7 0 0.3927 0.7854 1.1781 1.5708 1.9635 2.3562 Columns 8 through 9 2.7489 3.1416 You can use the colon operator to create a vector of indices to select rows, columns or elements of arrays.
• You see while it's running, MATLAB says that it's busy. Sometimes it will be busy and you won't even see it. Let's try that again. X equals 1 while 1--now I'll do it with a semicolon, so I'll suppress output, but it will still be doing it. End. So now MATLAB is busy. It's not typing anything on the screen, but it's doing the same calculation ...
