3d bar from scattered data
Dear all, I have a matrix of scattered data (x, y, z). I was wondering if there's a way to plot 3d-bars based on the z-values for each (x,y) pair. In a way, it's similar to plot3, but instead of plotting just the points, I would like to plot bars. Best wishes ... 23 Apr 2010 20:54

Linear combination of linearly independent rows/columns of matrix
Dear Sir, I am new to Matlab and this is my requirement: I have a rectrangular matrix m x n, with rank n. I want to find how the remaining m-n columns/rows, each one is a linear combination of 'n' linearly independent rows. Is it possible to find that thru MATLAB? Please help.

Rsquare for polyfit
Hi everyone, I'm a MatLab greenhorn, so excuse me if my question seems too simple. I've been failing for hours to solve it. Within a small MatLab routine, I'm fitting a linear function to a data set of four x and four y values, using coefficients = polyfit (x, y, 1). I'd also like to know the coefficient of deter... 23 Apr 2010 20:55

For me its unclear what I have to enter there when I connect the xPC target via RS232 to the host PC. On the target screen I don't see any interrupt line from the CPU. If I choose an IRQ then the m... 23 Apr 2010 20:54
