Conversion of complex number in to fixedpoint representation

i want to convert array of complex number in to fixed point (Q1.14) . how to do this things

(0.5590 + 0.1757i,
 0.1771 + 0.9121i,
   0.9884 + 0.1842i,
   0.4145 + 0.8949i,
   0.1781 + 0.0133i,
   0.8541 + 0.2089i,
   0.6628 + 0.1040i,
   0.5400 + 0.5972i,
   0.4648 + 0.0715i,
   0.3596 + 0.8972i,
   0.3479 + 0.9052i,
   0.3308 + 0.7455i,
   0.7069 + 0.2999i,
   0.7640 + 0.2425i,
   0.0567 + 0.1967i,
   0.4460 + 0.6754i,
   0.8985 + 0.7363i,
   0.9995 + 0.1341i,
   0.8182 + 0.0538i)

i wrote code for this but i don't know it is right or not

my code is

fid = fopen('1.txt', 'rt');

x = textscan(fid, '%f');

fprintf(fid, '%f%+fi\n', real(x{:,1}), imag(x{:,1}))

fclose(fid);

x{1}

%%convert complexdata into 32bit binary

re = real(x{:,1});

im = imag(x{:,1});

n = uint32(((re<0) + abs(re)) * 2^15) * 2^16 + uint32(((im<0) + abs(im)) * 2^15)

d=dec2bin(n(:,1),32)

Are you familiar with fixed-point numeric objects ?

[stuti]

yup sir. in Fixed point format

Sign bit- integer part- fraction part

where i want 1 or 2 bits for integer and rather bits in fraction part.

An example:

 clear; clc; close all;

% a complex number
x=0.3435637634857634+1i*0.66735646778675;

% parameters for fixed point conversion
wordLength=15; 
sign=0; % unsigned numbers
fractionalPart=14; 

% covertion to fixed point
X=fi(x,sign,wordLength, fractionalPart);

% how to access values
Xre=real(X);

disp('binary word:  ');  disp(Xre.bin); fprintf('\n');
disp('real world value, as a string:  '); disp(Xre.Value); fprintf('\n');
disp('fixed point value:  '); disp(Xre.data); fprintf('\n');

% comparison with floating arithmetic values
disp('----------------');
disp('rounding error:   ')
disp( X.data-x )

Conversion to fi-objects is controlled from muny parameters, I suggest to have a look at mathwork's help files
