how to transfer data from Proteus to Matlab? (Serial Communication)

Hello, Im currently working with two softwares mainly Proteus and Matlab. I want to send a wavefrom from Proteus to Matlab through a com port. I did test my com port with proteus by sending data from matlab to proteus but im unable to send data from proteus to matlab, and error occurs as shown in the picture. Can you please assist me with sending this data / waveform from proteus to matlab via the port.?

did you tried like this?

port = 'COM1';
text_send = 'HELLO';
s1 = serial(port,'BaudRate',9600);
fopen(s1);
fprintf(s1,text_send);
fclose(s1);
delete(s1);

try this one

port = 'COM1';
s1 = serial(port);
set(s1,'BaudRate',9600,'StopBits',1,'FlowControl','none','Parity','none','DataBits'...
    ,8,'outputBufferSize',5000); 
s1.InputBufferSize=5000;
s1.TimeOut=5;
fopen(s1);
out = fread(s1);                   
fclose(s1);
delete(s1);
