I have used Embedded matlab function in Simulink ,three have written code for a sinewave,when i use scope i do not get sine wave i just get many straight lines ,please help

t=0:0.1:10;y1=sin(4*t);
y=reshape(bsxfun(@times,repmat(y1,3,1)',[1 3 5]),1,[]);
my stop time is 0.5 , i need increasing sine wave as like that code

Pat, that's what I was expecting, the size of y is [1 303], that means your output will be a vector of 303 elements which will be displayed in your scope. Why are 'nt you using a sine wave block ? what do you to get exactly?

Azzi i need a increasing sine wave in simulink ,as like the output of above code but my stop time must not exceed 2

If your stop time is 0.5, with sin(4*t), the period is pi/2, which means in 0.5 s you will display only a half period of a sine wave

ok Azzi can you tell how to get increasing sinewave in simulink,with stop time less than 2s

use 3 sine wave block with different amplitudes through a multiport switch, then set your frequency to at least 10 Hz

Azzi i used 3 sin blocks with constant as 2 ,but i get one sine wave as below,i have set amplitudes ro 1,2,3 respectively and frequency(rad/sec)to 10000,but it is decreasing and increasing
my mdl is

Set the stop time to 1.99, the frequency of each sine wave blck to 56 Hz. The amplitudes to 1, 2 and 3
In configuration parameter set the fixed step size to 0.001
