using for loop in alignsignal function

I am using the function [Xa,Ya] = alignsignals(X,Y). Now I want to perform this operation on an arry of X and Y's and store them on Xa's and Ya's. Any suggestions. Here X and Y will be a matrix instead of a single vector.

Here is my code which does not work :

d1=resample(data,25,200); %% here d1 is my matrix and I want to align signal1 with each of the columns of d1.

for i=1:size(d1,2)

%[Xa(i),Ya(i)]=alignsignals(X(i),Y(i));

[xx(i),yy(i)]=alignsignals(signal1(i) ,d1(:,i));

end

%I assumed both (X & Y) have same lengths

for i=1:lengths(x)
[Xa(i),Ya(i)]=alignsignals(X(i),Y(i));
end

For example

y1=[1 2 3 4];
y2=[4 5 6 7];
x=[];
y=[];
for i=1:length(y1)
    [x(i) y(i)]=fun4(y1(i),y2(i));
end

fun4

function [x y]=fun4(a,b)
x=a+b;
y=a-b;
end

If I misundestood your question, let me know.

Thanks ACHARJYA, but my Y is a vector and X is a matrix ( say X1,X2,X3). Now I want to alignsignals Y and X1, Y and X2 and so on ...

I always get this error : Unable to perform assignment because the indices on the left side are not compatible with the size of the right side.

@Debanjan data?

[Debanjan Borthakur]

data is just a matrix (2961*258)

[KSSV]

[m,n] = size(X) ; 
Xa = zeros([],m) ; 
Ya = zeros([],n) ; 
for i = 1:n
    [xa,ya] = alignsignals(X(:,i),Y(:,i)) ;
    Xa(:,i) = xa ; 
    Ya(:,i) = ya ; 
end

If function is shown...may be it can be vectorised and work for entire matrix.

hi, your first line results error : Too many output arguments.

[Debanjan Borthakur]

d1=matrix (2961*258)

n=258

m=n

Xa = zeros([],m) ;

Ya = zeros([],n) ;

for i = 1:n

[Xa(1:length(M_1norm),i),Ya(:,i)] = alignsignals(M_1norm,d1(1:length(M_1norm),i)) ;

end

Unable to perform assignment because the size of the left side is 0-by-1 and the size of the right side is 3292-by-1.
