Nevermind, I worked this thing out I don't want Matlab code I just wanted to do it by hand, an analytical solution Matlab is worthless for giving insight into a solution, but it will provide you with a numerical solution...if you don't understand how it works and why it works the solution...

manual, hand solution.. btw I realized I typed a small error... the second part of R(t) should read E*(exp)^(-k(t-Tm)), t>Tm where t is the variable of integration and Tm is a constant

Touche! my best teachers were definitely my Uni profs, and they didn't take any BEd training...maybe that's why...because even the Bachelors of Education programs spout off so much garbage that I rarely attended...I can still remember getting the email, informing me of my extremely poor...

dont fret about the delta functon, its just delayed so that the input will be definted for the instant you are interested in! you want to start by defining the 4, 4x1 vectors in your program: say v1, v2, v3, v4 define the 4x4 matrix 'MMM' in the same fashion your desired vector can be...

Yeah I agree! Standardized testing, first off is never standardized, there are so many reasons to believe that make it impossible that everywhere in a state, the students are prepped for the test the same way, therefore, the distribution of peformance will not infer in most cases that all...

10 light years is the time length according to the moving frame, but what about the distance is that the distance you percieve in the moving frame or is that the distance from the rest frame, according to an observer on Earth?! If 130pc is the length observed in the moving frame then...

I was a high school teacher in Ontario Canada for 3 years..I couldn't find a full time job in the area that I wanted to work in so I decided to go back to get my PhD i nMedical Physics. A top earning physics teacher in my former school board made about $85 K CAD a year, there is no pay...

SORRY, I figured it was wrong of me to hijack someone elses thread with my query so I will start my own thread, my apologizes in advance for I will also post a thread within the Math forum... I am new here and I bring a similar question for my first post... I want to know how to do a...

can you provide a few more details, I don't understand the represntation, but I can help you!

now this is good!

I think the simple answer to the original question was answered in one of the first replies...I didn't read every page so I apologize if I sound like an earlier response I just felt liek throwing my 2 cents out quick! The assumption that you have an infinite number of events in the time...

[FONT="Courier New"] Nice Job! I am new here and I bring a similar question for my first post... I want to know how to do a convolution where the two functions are: Ca(t) - arbitrary Input function (it actually represents the time activity curve of a CT contrast bolus injection in...
