I am getting an error "not enough input arguments" even though i have given command [a,b]=my_conv[[1 2 -1 4 3 -2] ,[-1 0 4 3 1] , 2, 2] for the function given below, HELP me

function [y,yz]=my_conv(x1,x2,z1,z2)
%output zero
yz=-(-z1+1-z2+1)+1;
%output length
ylen=length(x1)+length(x2)-1;
y=zeros(ylen);
x11=[x1,zeros(length(x2))];
x22=[x2,zeros(length(x1))];
for i=1:ylen
    for j=1:i
            y(i)=y(i)+x11(j)*x22(i-j+1);
    end
end
end

%  these should be round to make sure it is valid Matlab syntax

Error in solution>my_conv (line 8)
x11=[x1,zeros(length(x2))];

Did you do a basic Matlab tutorial?

[Akash Reddy KANKANALA]

is there anything wrong with my function?

Did you try running it yourself? Then you will ge the same error.

You could check the edits Chien made in his answer.

% [a,b]=my_conv([1 2 -1 4 3 -2] ,[-1 0 4 3 1], 2, 2)

%output length
ylen=length(x1)+length(x2)-1;
