I have 468 by 1 matrix of floating data. I need to convert it to binary with same dimensions, e.g., 468 by 1. Kindly help

-1.9836
 -0.0287
 -0.4330
  0.7517
 -0.4883
 -0.1712
  0.2263
  0.7347

convert it binary with same matrix dimensions

[Guillaume]

Most likely, you don't even understand what you are asking since it is very unlikely that a 468x1 binary array would make any sense. In any case, you need to explain what is the rule to convert your array to binary.

Here is one way to convert your array to a 468x1 binary array:

result = randi([0 1], size(yourarray);

Here is another way, probably more useful:

result = yourarray > 0;

Neither are probably what you're after but how are we to guess?

@Guilalume: well, the numeric data shown in the question is already a binary array, and seems to fulfill all of the requirements so far. Perhaps the question was asked without realizing that numeric arrays are already binary...

[Guillaume]

Yes, I think it's a case of the OP not knowing what binary is. However, considering the complaint that Kalyan's answer generates an 8 column matrix, it does look like the OP is after a column vector of 0 and 1.

Hope this is helpful, for example

a=[-1.23;-2.54;-1.50]

    a =    
       -1.2300
       -2.5400
       -1.5000

    >> d=dec2bin(typecast(int8(a),'uint8'))

    d =

    11111111
    11111101
    11111110

it is returning 468 by 8 char values while i need 468 by 1 double(binary) values. kindly guide

[Stephen23]

@Sajid Sarwar: and what exactly are "... 468 by 1 double(binary) values"? Perhaps you know what this is, but we don't.

Please give us an example of a "double(binary) value". Show us one.

[KALYAN ACHARJYA]

Agree with @Stephan Sir, you have to clarify.

No its 468 by 1, if you convert it -1.2300 to binary, then 11111111 considering a single 8-bit number.

[Sajid Sarwar]

I have matrix with floating elements of 468 by 1 type double which I have posted in my question. I need to convert it into binary with same dimensions e.g., 468 by 1 type double.

[Sajid Sarwar]

@KALYAN ACHARJYA sir the example you have provided give me output of 468 by 8 char type but i need output with 468 by 1 double type

[James Tursa]

You need to give us an explicit example of what you mean by a "double binary" type. Technically, MATLAB stores the double value in floating point binary already, so what is it that you actually want? E.g., if the double value is 1.5 then what would be your desired output?

[Stephen23]

@Sajid Sarwar: I guess you did not read my request. Here is what I asked you:

Please give us an example of a "double(binary) value". Show us one.
