Write a Matlab code to compute the Frobenius norm of a matrix. Use it to compute ||A|| and
||B||. Show your results and attach code. (Do not use the Matlab built-in function norm.)

Hello

I have this function

function P=square(a,b,c,d)
clf
axis([a b c d])
hold on
hnappur=1;
while hnappur==1
[x,y,hnappur]=ginput(1);
if hnappur==1
plot(x,y,'o')
end
end

It puts up a picture and I can click on it to plot single points. I want to add to this function that it can read four points that I click, and draw a rectangle between them. How do I make matlab read the point that I click?

Thank you so mutch for your help

I am a final year engineering student and am working on a project in audio processing. i have designed a program in Matlab regarding my project and now to implement it in a hardware unit i need to convert it into C programs
can someone help me in conversion of programs from Matlab to C

random walk. by a complicated set of deals, you have arranged that after 28days you will gain £f(Y(28))=£(5-|Y(28)+3| million. thus is Y(28)=-2 you gain £4 million Y(28)=5 you lose 3 million and if Y(28)=2 you break even
estimate your gain using mathematica for y=1,2....28
