Unable to perform assignment because the indices on the left side are not compatible with the size of the right side

I am confused yet . I hoped to get string (i dont know what i have to say character or string) values for every matrix elements but i didnt happen.

Example- Input=[1.25 2.2;3.5 6.2] and Output=['1.25' '2.2';'3.5' '6.2]

Can anyone explain me please, whats the error inside the code ?

%Code

function y=elementsnumber2string(x)

[m,n]=size(x);

y=[];

for i=1:m

for j=1:n

y(i,j)=num2str(x(i,j));

end

end

end

%Output

Unable to perform assignment because

the indices on the left side are not

compatible with the size of the right

side.

Error in findafterdecimalponts (line

6)

y(i,j)=num2str(x(i,j));

use { } in 6th line. that will work.

It doesnt work brother :(

y(i, j) refers to exactly one element of y as you've defined i and j. How many elements does, say, '10' have?

numel(num2str(10))

You can't fit two characters into a space big enough to hold one.

Depending on which release you're using and how you want to use y, what you're trying to do could be as simple as calling string on the matrix x.

x = magic(5)
y = string(x)
y(2, 4)

Thank you for replying . But i want single quotes rather than double ones like '1' like character.

I want to do the operation like this along a whole matrix .

x=2.2

num2string(x)

ans= '2.2'

Can i do that? is it possible ?

Actually i want to convert the x=[1.25 2.2;3.5 6.2] matrix into a character matrix (array) like y=['1.25' '2.2';'3.5' '6.2]. Then i want to define the max decimal points that the character has among all the character.

How would i do that ? Any idea please
