Thanks for the reply. The second program is another m-file and I wanted to use the movie as the input. The program was supposed to count the number of zeros and ones in each row and average them for each frame. The problem is instead of a 200 by 200 matrix the structure files are 343x435x3. I...

Hi, I made an m-file which which outputs movies at the end. The movie frames are made from images of a 200 by 200 matrix. I wanted to input the movies into a second program which then analyzes each frame. The problem is the frames are structure files and I don't know how to convert the frame...

I'm trying to write an m-file in MATLAB that can count how many data point in a vector are zero, how many are 1, etc. I can call the vector and get the length, max and min values, but I also need to be able to call each element seperatly and I can't figure out how to do this. I've been playing...

sorry about that mess with the sigma sign in the middle, I tried to edit it but it was going to delete it. I guess it will take a little practice writting with that stuff.

Yeah, I see what your saying. I tried it out after I posted. The problem is I don't have an end number to evaluate it at, but I have a formula for \sum\ limits_{K=0}^n K. I'm thinking because there is no no number to evaluate it at that the answer is just a general formula, like n(n+1)/2 but our...

If I have a problem like (N) sigma (K=0) Cos(Kpi) can I just move the sigma sign inside the brackets? like Cos(pi Sigma K) just wondering because I have this on an assignment problem and we didn't learn it in class and the textbook doesn't cover it either. If I can move it inside...

This is the problem: A 235g block is pressed against a spring (with K=1.32KN/M) until the block compresses the spring 10.0cm. The spring rests at the bottom of a ramp inclined at 53.4deg to the horizontal. A) Using energy considerations, determine how far up the incline the block moves...
