Recorded signal file with .sig extension and plotting the signal

Question

I have a recorded signal file that contains a vector of values containing samples in the form of real and imaginary parts. I need to plot this signal in matlab. Maybe someone faced such a problem.

I can't attach a file, so here is a link to Google Drive

L = 150;
header = struct('DataType','double',...
    'Complexity',false,...
    'FrameSize',L,...
    'NumChannels',1);
writer = dsp.BinaryFileWriter('2665-0.sig',...
    'HeaderStructure',header);
 
sine = dsp.SineWave('SamplesPerFrame',L);
scopewriter = timescope('YLimits',[-1.5 1.5],...
    'SampleRate',sine.SampleRate,...
    'TimeSpanSource','Property',...
    'TimeSpan',1);
 
for i = 1:1000
    data = sine() + 0.01*randn(L,1);
    writer(data);
    scopewriter(data)
end

Answer 1

It was a task to get signal analysis data into the Workspace. After this signal can be obtained in Signal Analyzer: https://docs.exponenta.ru/signal/ug/visualize-complex-signals.html

clear all;
close all;


global N_data;    %??????????? ?????????????? ???????? 

N_data = 1048576;   %??????????? ?????????????? ???????? 
i = sqrt(-1);


% ????????? ?????? ??? ???????? ??????? ? ??????????? ??????? 
op = zeros(1,N_data,'single')+i*zeros(1,N_data,'single');
kontrol = zeros(1,N_data,'single')+i*zeros(1,N_data,'single');


ima_faila = char('file's name');
ima_faila = strcat(ima_faila,'.sig');

signal = fopen(ima_faila,'rb');
if signal == -1
    error('net faila');
end

            input_s = fread(signal,N_data*4,'int16');
     
 op(1:N_data) = input_s(1:4:N_data*4)+i*input_s(2:4:N_data*4);      % ???????  ?????? ?? ?   
 kontrol(1:N_data) = input_s(3:4:N_data*4)+i*input_s(4:4:N_data*4);   %   ???????????  ????? ? ?
