Does Matlab support strcpy?

I was just wondering if Matlab support strcpy. In writing a program and I want to cot a string and I was wondering if I could use strcpy which is a C command. So far it does not give me an error but it's not doing anything either

Could you provide an example of what you want to do? If it is just concatenation with e.g. "", you can do something like
quotedStr = ['"', initialStr, '"'] ;
or
quotedStr = sprintf('"%s"', initialStr) ;
Ah, if 'cot' was 'cut' and not 'quote', you can index a string like a numeric array..
>> myString = 'Hello World' ;
>> myString(1:5)
ans =
Hello

strcpy is not a matlab function, and it should give an error, how are you using it?

Looking at: strcpy (and not being a c++ expert) it looks like you don't even need it. MATLAB passes by reference automatically, so just:
str2 = str;
would do the same thing.

This is not a valid Matlab program. Checking the reply of FGETS to differ from 0 is a bad idea, because strings are allowed to contain zeros in Matlab and WHILE isnerts an all() implicitly when its argument is a vector. And then even Strcpy() is not a valid Matlab command.

while 1 % Infinite loop
line = fgets(fid);
if ~ischar(str)
break;
end
array = line;
... process the array here
end
I assume your concept of using STRCPY is not useful in Matlab.
Btw, I used "line" to be near to your example. But it ios recommended not to use the names of built-in functions in real programs.
[EDITED] Perhaps you want:
fid = fopen(FileName, 'r');
A = fscanf(fid, '%f', Inf);
fclose(fid);

"array{k} = array{0}" is simply confusing. Do you want "array" to be a cell? If not, please do not use curly braces in a Matlab forum. In addition Matlab's indices are 1-based, so there is no element with index 0. Neither "then copy it" nor "print it" are clear. And "Sscanf(array{0},%f,var)" is still mysterious for me. So please explain, what you are trying to do without using another language.
Terms like "Tryna" might be kewl, but they are hard to understand for non-native speakers.
