Lesson 6.2 while-loops in MATLAB

[@iqhamad6368]

You are an excellent teacher, I never saw a teacher like you. I never find a teacher in my life like you are. Great respect and salute from Pakistan

This is the first time that I know about the difference between for and while loops. When I was study in the college, I thought them the same and thinking why we use for, while and do while...! Thank you very much professor. This is the best MATLAB MOOC ever.

PLEASE CORRECT ME IF I AM WRONG • ONE OF THE MAIN THINGS WE NEED TO TAKE CARE WHILE DIFFERENTIATING BETWEEN THE FOR LOOPS AND WHILE LOOPS IS THAT  IN FOR LOOPS WE CANNOT CHANGE THE VALUE OF VARIABLES OF THE LOOP INDEX FROM THE BODY STATEMENTS. BUT IT IS NOT THE CASE WITH WHILE LOOPS. YOU CAN CHANGE THE VALUES OF VARIABLES THAT SERVE AS CONDITION OF WHILE LOOP

[@fitzlellc3599]

You can change the loop index in a for-loop, but you should not and it is temporary anyways :-) . The main difference is that a for loop has a fixed number of iterations, while a while loop does not.

somebody correct me please! I've gone over the irritation of square root of 2 and the only way I've got each value of the function while using a calculator it was if I used y=2 and squared it than subtracted the x which is equal to 2.

how is the approx_sqrt() function near to build in function? I don't get that.

hi, I have a exercise, find the index of a given value belonged to a function( for example, s=sin(t)), I made it with while-loop, easily, but I don't know how to match them.( because the function is symmetric, so there're 2 indeces for one value, I have a low_index function and high_index function.) can anyone tell me how I can match them ? here are my functions :( I eased my original problem) function hl=cal_lowf(slow) t=0:0.001:2*pi; s=sin(t); [smax f0]=max(s); f1=f0; while smax>=slow f1=f1-1; smax=s(f1); end ------------------------------------------------------- function hh=cal_highf(shigh) t=0:0.001:2*pi; s=sin(t); [smax f0]=max(s); f=f0; while smax>=shigh f=f+1; smax=s(f); end

+Quyền Đặng Cao You could match them by plotting the first, then typing >>hold on then plotting the second?

MATLAB nobody likes a showoff :)

hi there, what about ' return'

Exactly

Molto interessante, suggerisco anche il corso grautito di "Corsi Consulenze NPR", kzbin.info/www/bejne/pJSUq55meaZ9pJI
