How to cut a slice through a matrix?
Hi. I have done a simulation where I calculate a certain value (v) for all combinations of three input values (x, y, z). These are currently represented in the variables X, Y, Z and V which are all three-dimensional mesh-grid-style arrays. Now, I realize that variations of the variable Z are not so interesting, bec... 7 May 2010 07:48

How to remove one cell from a cellarray ??
I have this : SX = [] 'y1' 'x2' 'y2' 'x3' 'y3' [] [] 'x5' 'y5' How can I remove empty cell [] which results : SX = 'y1' 'x2' 'y2' 'x3' 'y3' 'x5' 'y5' then I can call for example : SX{3}='x2' ... 7 May 2010 05:37

Differential equations
Hello everyone, I'll be very thankful if someboby helps me: I need to solve a system of two differential equations, quite complicated and face that ode45 spends hours and cannot solve it. I tried ode113 for 6 hours, cpu was loaded on 100%, but no result. Is it ok for solvers to work so long? And since I have not got r... 7 May 2010 04:33

How to correct phase of a system?
Hey, I was wondering if someone is able to help me with the following problem: I obtained a MIMO system sys by linearizing (with linmod) a nonlinear simulink model. Someone the phase of this system is not correct... For example, the transfer from input 1 to output 1 looks as: mag | -----------------... 7 May 2010 03:28

Need help using erfc
I'm doing a statistics project and when using the erfc, I get a value my professor tells me is wrong. "1-erfc((-.5/sqrt(.01/3))/sqrt(2))/2 = 0" I know that the real value is close to 0, but isn't actually 0. It's something on the order of 2*10^-15 or so. How can I get MatLab to give the the correct value?... 8 May 2010 14:30
