In MATLAB you do not not have to declare a variable and its type. The type of a variable is specified through its initialization. So you choose a name for the variable and use the equal sign to initialize it. If no semicolon is used at the end of a command, MATLAB gives feedback about the initialized variable. Otherwise no output is generated. Scalar values for example are initialized like follows:
An n-dimensional vector is created by typing the n components in rectangular brackets. Seperation of the values with space leads to a row vector while values seperated with a semicolon result in a column vector.
To compute the magnitude of a vector use the command norm:
