blockproc
Hello to everybody and thank in advance. I have some pictures and i want to divide them into blocks of 9x9. I have found that blockproc can help me for this task but my problem that i can t understand how does work. I wrote to matlab something like that I2 = blockproc(J,[9 9],fun); where J is my picture and then i rece... 13 Apr 2010 08:20

Multiplying factor through cell array
I'm sure there must be a neat way to do this, but I can't see it. Can anyone help? I've got a cell array like this: {0.7,0.5,{0.6,0.8}} Or this: {0.8,{0.3,{0.9,0.9}},0.3} I want to multiply these cell arrays by an array of factors of the same length, where the factors are multiplied through any embedded cel... 12 Apr 2010 21:27

Input data dependency violation due to action subsystems. See Subsystem Examples in the Simulink library for valid and invalid examples of action subsystems
Im trying to connect an "If Action Subsystem" block to a "Multiport Switch". Im using an edge activated counter to feed into the control input of the Multiport switch. I get the error warning "Input data dependency violation due to action subsystems. See Subsystem Examples in the Simulink library for valid and in... 12 Apr 2010 20:21

finding remainder and quotient of transfer function
I have a TF which has a numerator larger than my denominator. I used the following code to determine the remainder and quotient. In the end I want a plot of the remainder divided by the original denominator with a y-shift by the quotient. v=[0.1741 137.8 511.8 888.8 662.1 166.9 0 0];%numerator of original TF u=[0... 12 Apr 2010 20:21

integration interval of standard normal
i'm trying to estimate an integration interval for the indefinite integral of a standard normal distribution such that the result has 10 decimals of precision. what's the best way to do this for this integral (or for any integral in general)? is it basically a trial and error process using a quadrature rule (quad, tr... 12 Apr 2010 19:14

NI PCI 6220 ADC board
I have attempted to use the solution posted here, but unfortunately I've been unable to get any signal from the simulink block. I've tried changing the block settings to match the non-xPC 6220 A/D board, changing the voltage input range, using differential signal mode, adding all 16 channels and looked at all of the... 13 Apr 2010 09:26
