A simple while loop to display numbers from 1 to 10 is shown here. A condition is true if it is not equal to ‘0’. In the following example odd numbers from 1 to 9 are printed.ġ0 while loop While loop continue to execute if the given condition is true. We can increment the control index by any arbitrary value as required. We don’t need to initialize scalars in MATLAB.ĩ for loop (contd.) The control index of the for loop shown in the previous slides was incremented by ‘1’. Note that this is the case for vectors and matrices only. The vector must be initialized before assigning any value to it. Note that the squared values will be saved in the ‘result’ vector. Now we are saving the results in a vector named ‘result’. In matrix form the above system and its solution can be written as In MATLAB we write as x = inv(A)*bĦ Loops Two different types of loops exist in MATLAB.įor and while Their structure is as shown hereħ for loop A simple for loop to calculate and display squares of numbers from 1 to 5.Ĩ for loop (contd.) We can write the same for loop with some change. Note that vectors are special case of matrices.Ĥ Matrix Calculations Addition Multiplication InverseĪ=matrix of coefficients, x = vector of variables, b = vector of values. A vector of length n can be visualized as matrix of size 1xn or nx1.Ģ Vectors and Matrices Matrices can be of different sizes, either square matrices of size NxN or rectangular NxM. A vector of length n can be visualized as matrix of size 1xn."- Presentation transcript:ġ Vectors and Matrices In MATLAB a vector can be defined as row vector or as a column vector. Presentation on theme: "Vectors and Matrices In MATLAB a vector can be defined as row vector or as a column vector.
