Hi,
Consider we have two row matrices x and y. Both matrices have the same dimension 1 by m. I need to write a new string matrix z as z=[(x(1),y(1)),(x(2),y(2)),...,(x(m),y(m))]
Appreciated any help!

Not entirely clear on exactly what output you want.
If you have indeed two string vectors, e.g.:
x = ["one", "two", "three"];
y = ["four", "five", "six"];
then
z = compose("(%s, %s)", x', y')'
or something similar is probably what you're after.

For a simple case X=[1 7 4]; Y=[3 8 9]; What I want as output is: Z=[(1,3),(7,8),(4,9)]

Almost the same. Please try the following.
X = [1 7 4];
Y = [3 8 9];
Z = compose("(%d, %d)", X', Y')';

Thanks for your answer. This code results in "(1,3)" "(7,8)" "(4,9)" But I need exactly an output like Z=[(1,3),(7,8),(4,9)]. Z is originally a matrix of high dimension (1 by m where m is greater than 2000). So I don't wanna be bothered modifying the output by adding commas and deleting "s.

Do you mean that you need the output to be a single string object that starts with "Z = [", and then has all of those pairs in () with commas between them, ending in "]" ?

Yes, exactly. and please consider that I need a solution for Z with m pairs.

output = "Z = [" + strjoin(Z, ',') + "]";
where Z is as suggested by Akira Agata

Thanks Walter. This works.
