Shrinking Cell Arrays
I am preallocating a cell array because MATLAB suggested it for greater efficiency. In the suggestion box there was this sentence: "If you do not know the size of an array before the loop begins, preallocate it, and then if necessary, shrink it after the loop completes." I have been searching for hours and I have... 19 Feb 2010 12:06

help me please!!urgent
Hi! I'm a new user and I don't know how to export a tseries to excel. I have 74 tseries in a mat file. I wan't to know how I can convert my tseries to one single matrix of 74 columns. It doesn't matter if I can't include dates (I could add this afterwards in excel because all my tseries have the same range)...If you k... 24 Feb 2010 17:42

solve Ax=b
Hi, I have a (3355x2) matrix (called A) and a (3355x1) vector (called 'b'), and I am solving for x as Ax=b. I used x=A\b. However, when I multiply A*x, the solution is very different from 'b'. Does anybody know how to solve the problem? Can I use this the optimization toolbox to solve the system of linear equati... 18 Feb 2010 10:33

Shifting data
Hello, I want to start two graph's at the same y-value (trig) independent of there corresponding x-value so I can compare those graph's. So I've made a function which calculates the x-value of this y-value by interpolation. This gives me the exact x-value of the point of intersection. In a next step I want... 18 Feb 2010 10:33
