So in each loop, we need to index the matrix elements individually to assign these valus to a new matrix elements. In here, we want to convert a 3×4 matrix which is ‘x’ into a 4×3 matrix which is ‘D’ above. This example is about the priority of the for-end loops that coded inside themselves. You can obtain programmes for these new values in each loop, inside the for-end command in Matlab.Īnother example about for-end loop in Matlab x = So in each loop, the variable that assigned to for-end command will take a new values. As you see in the result at command window, 3 of elements has no imaginary section, so they are real, and the number that has imaginary section is 5. If there is no imaginary section(so it is ‘else’ in our code), the value of ‘real’ will be increased 1.Īt the end of the loop, we want to see the values of these two vectors. If the imaginary section is not zero that we stated in if command above, the value of ‘im’ will be increased 1(im=im+1). We asked this question with if-else in Matlab by indexing the each element of vector ‘x’ in each loop, inside ‘imag()’ command. element(which is the value of ‘y’ in current loop…) has imaginary section?” So, if we build a program that asks to the vector ‘x’, “Does your current y.
We said that in each loop, ‘y’ will take different values. To find out the imaginary element inside vector ‘x’, we created a if-else query. Once for-end loop reaches to 9, program will exit the for-end loop, and go on other codes after the for-end loop. In each loop, ‘y’ will take values starting from 1 ending at 8. For example, we created the vector ‘y’ for for-end loop above, that has elements of 1 to 9 inside it. To obtain for loop, you need to create a vector that has elements in increasing direction. These values will change inside for-end loop. In general, you need to give inital values to your variables that will be used in for-end loop in Matlab. These variables have initial values of 0. To do it, we created two of variables named ‘im’ and ‘real’ after the vector.
Assume that we want to create a program that finds the number of elements that has imaginary value and that has not imaginary value separately, of a vector in Matlab.Īssume that we have vector that has 9 elements inside it, and some of these elements has imaginary number. If you understand above program example that obtained in Matlab command window, you will learn the logic of for-end in Matlab. You can obtain loops for different queries to obtain algoritms in Matlab, by increasing the looped value in each loop by using ‘for’ loop.
