position/orientation question
I am given this question about the tacoma bridge collapse. For the first part you have to ask the user for two inputs, the wind velocity (in Km/h) and initial orientation (in degrees). Your program then has to calculate the position and current orientation over a time of your choice (and of intervals within that time ... 4 May 2010 02:26

copy cell array to matrix (w/conversion)
I have a 500,000 x 3 cellarray with the first col being a sql server datetime string Is there a better way than shown below to copy the cell array to a matrix of the same dimension while converting the first col values to datenums mat=zeros(size(ca)); for k = 1:length(ca) mat(k,1) = datenum(ca{k,1}) ... 4 May 2010 12:19

Change code to do iFFT
I wrote the following code to compute a FFT in MATLAB. I have it working, and have confirmed its accuracy using MATLAB's built in FFT function. My question is, how can I change this to do an inverse FFT? CODE: function f = myfft(p,data) %1 if 2^(p+1)>length(data) if floor(log(length(da... 3 May 2010 18:43
