Hi, I'm very new to MATLAB and I am having some trouble. Could somebody please explain what this error is and how to fix it?
Its written
"convolution requires more input arguments to run:
convolution(x,h)
enter input arguments by typing them now, then press Enter to run. The values you enter will be set as the default inputs when you click the Run button in the future."
let say i want to input x = [1 2 3 4]; h = [1 -1 1 -1];
where should i put it?
function [ Y ] = convolution( x,h )
m=length(x);
n=length(h);
X=[x,zeros(1,n)];
H=[h,zeros(1,m)];
for i=1:n+m-1
Y(i)=0;
for j=1:m
if(i-j+1>0)
Y(i)=Y(i)+X(j)*H(i-j+1);
end
end
end
yin = conv(x,h);
xaxis = 0:1:n+m-2;
subplot(2,1,1)
stem(xaxis,Y); xlabel('n value'); ylabel('y value'); title('Manual Convolution');
grid on;
subplot(2,1,2)
stem(xaxis,yin); xlabel('n value'); ylabel('y value'); title('Convolution using conv');
grid on;
end
