Almost all of matlab s basic commands revolve around the use of vectors.
How to logarithmiclly space vectors mat lab.
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.
To programmatically exit the loop use a break statement.
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.
Following example would demonstrate the concept.
Define the function y f x call the plot command as plot x y.
If a is a vector then sum a returns the sum of the elements.
A matrix is a two dimensional array of numbers.
If a is a vector then mean a returns the mean of the elements.
Lin in the name linspace refers to generating linearly spaced values as opposed to the sibling function logspace which generates logarithmically spaced.
To iterate over the values of a single column vector first transpose it to create a.
This dimension becomes 1 while the sizes of all other dimensions remain the same.
Note that matlab printed out a copy of the vector.
Code a cell array by listing a series of numbers vectors or characters in the same format as a matrix while characters are in quotation marks and vectors are in brackets.
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.
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.
If a is a matrix then mean a returns a row vector containing the mean of each column.
The for statement overrides any changes made to index within the loop.
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.
To skip the rest of the instructions in the loop and begin the next iteration use a continue statement.
V 3 1 v 3 1.
Linspace is similar to the colon operator but gives direct control over the number of points and always includes the endpoints.
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.
A vector is defined by placing a sequence of numbers within square braces.
If a is a matrix then sum a returns a row vector containing the sum of each column.
This creates a row vector which has the label v.
This dimension becomes 1 while the sizes of all other dimensions remain the same.
