matlab - Updated :Technique used to control Step sizes (Quantization levels) of signals -


i have 2 nonlinear signals generated sensors taken different drives. wanted ask possible change or control step size of signal in matlab.

my aim make step size of 2 signals same though generated sensor possible through matlab , how.

what mean step sizes quantization steps shown in figure.

enter image description here

thanks lot.

how control step size of signal in matlab.

what want do.

  • i want down sample signal on decimal points .

  • change step size of signal.

for downsample have tried far .

  • decimate

  • downsample

but these commands works integer values if have decimal values should .

so thought of subtracting values samples . take example..

   ref=[1 2 3 4 5 6 7 8 9 10];    x=  ref(1:3:10)

this lessen samples desired values , change these decimal values also.

2nd step:

i want control step size of signal.

let’s suppose original signal has step size of 0.044 , measured signal has step size of 0.10.

i want make step size of original signal equal measured signal. (how possible).

i sorry not being able provide u original data has lot of values.

interpolation of signal way explained. there other way without interpolation?

because don’t want change data values want resolve issue values have.

for first question, can interpolate data using interp1 function?

in second question, i'm not familiar function, has bandwidth property. property want?

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
