MATLAB: Structure as input

input

Hello, I have a mat file where i have defined for structures and the time. The structures represent four bits and the value of the bits change at time because they represent a phone number. I want to convert the input signals that are almost rectangular in the numbers they represent, ie, if the values ??are (bo = 0, b1 = 0, b2 = 0, b3 = 1) the number of output should be 1 . The goal is to add a mobile number. Each digit is represented by four bits.

Any idea??

b0 * 8 + b1 * 4 + b2 * 2 + b3

You are making the mistake of providing poor starting values. You simply needed to provide a set of more intelligent starting values.

Just looking at your curve for some wild guesses...

B0 should be roughly 0
B1 should be roughly 10
B2 should be roughly 2*pi*10
B3 should be roughly 0.22

I'll predict that B2 was the only one that really mattered though. Regardless, all of those starting values are trivial to estimate programmatically.

>> str = {'a1','a2','a3','b1','b2','b3'};
>> vec = sscanf([str{:}],'%*[ab]%f',[1,Inf])
vec =
  1  2  3  1  2  3
>> vec = str2double(regexp(str,'\d+$','match','once'))
vec =
  1  2  3  1  2  3
>> vec = str2double(regexprep(str,'^[a-z]+',''))
vec =
  1  2  3  1  2  3
