- there will be a warning saying that "your matrix dimention is changing each time you run the file", but thats something that we want and its ok
- also for your matrix column , u can set a fix number like 10(the longest world length that will be in your file)
make a matrix out of list

I have a file which has 4 words such as
mini
miny
milky
mouse
It could also be a file with more words, but one word per line.
I would like to after reading from the file, which might could be done with load('file.txt'); command,
make a matrix that is as long as I have words in this file.
so if I have 4 words, then the matrxi H shall be 4 rows long.
Is it a possibility?

hi
i think its possible
declare a parameter like i=1 (showing which row u are in)
make a loop to read all of your file and detecting the end of it as a break
make another loop inside of it for reading each line and detecting the end of it for break(i think it was parameter \0)
as u read the word in second loop put it in your matrix (use another parameter like j=1 for declaring your column and increase it each time you end the second loop)
increase i after getting out of the second loop to move to the next row

It's not really clear if you want the contents of the file to be read into an array, or whether you just want a numeric (or other unspecified) array with the same size.
Assuming the first case:
fid = fopen('fruitwords.txt','r');
A = textscan(fid,'%s');
fclose(fid);
A{:}
If it's the second case, the simple way would be to simply read the file as above and then use the size of A to allocate a new array.
mynewarray = zeros(size(A));
This may be expensive if the file contents are unneeded or cause memory burdens. Trying to accurately and efficiently get line counts might be a bit more complicated otherwise:

Read about importdata. You can import the data into MATLAB, the data will be a cell array.
S = importdata('myfile.txt') ;
celldisp(S)
