A matrix is a two dimensional array of numbers. If a is a vector then sum a returns the sum of the elements. Y linspace x1 x2 n generates n points the spacing between the points is x2 x1 n 1. Avoid assigning a value to the index variable within the loop statements.

In matlab you create a matrix by entering elements in each row as comma or space delimited numbers and using semicolons to mark the end of each row. To define a column vector you can either separate every element with a semi colon or you can define the vector and use the transpose function as we will see in the following sections. The for statement overrides any changes made to index within the loop. Vectors in matlab are not the same as in every other programming language because the indexing starts from one instead of zero which means that the first value has the index one.

To plot the graph of a function you need to take the following steps define x by specifying the range of values for the variable x for which the function is to be plotted. If a is a matrix then mean a returns a row vector containing the mean of each column. A vector is defined by placing a sequence of numbers within square braces. This creates a row vector which has the label v.

If a is a multidimensional array then mean a operates along the first array dimension whose size does not equal 1 treating the elements as vectors. Define the function y f x call the plot command as plot x y. To skip the rest of the instructions in the loop and begin the next iteration use a continue statement. To programmatically exit the loop use a break statement.

If a is a matrix then sum a returns a row vector containing the sum of each column. To iterate over the values of a single column vector first transpose it to create a. V 3 1 v 3 1. Almost all of matlab s basic commands revolve around the use of vectors.

The first entry in the vector is a 3 and the second entry is a 1. This dimension becomes 1 while the sizes of all other dimensions remain the same. Lin in the name linspace refers to generating linearly spaced values as opposed to the sibling function logspace which generates logarithmically spaced. If a is a vector then mean a returns the mean of the elements.

If a is a multidimensional array then sum a operates along the first array dimension whose size does not equal 1 treating the elements as vectors. A cell array is a rectangular set of data similar to a matrix but it can hold any type of data such as text numbers and or vector. Note that matlab printed out a copy of the vector.
