Hi all,
I have a function called details, where the user enters his name, and the details are stored in the array, say "name". Each time a name is entered it should get appended to the array.
At any point, the user can cancel entering the details and do other computations. Then again the user can start entering the details. In this case, it should get appended to the "name" array that is already existing.
At the beginning of the session, the array "name" should be empty.

Create a 3x3 matrix A in which all the elements are 1, and create a 2x2 matrix B in which all the elements are 5. Then, add elements to the matrix A by appending the matrix B such that A will be:
A = [ 1 1 1 0 0; 1 1 1 0 0; 1 1 1 0 0; 0 0 0 5 5; 0 0 0 5 5]
I need to slove it .

Hi,
A possible solution to your problem could be something like this. Set the array as empty initially(beginning of the session).
nameArray = {};
You can then append the entries in the array as follows:
nameArray = [nameArray, 'Name you want to append'];
This uses the concept of cell array. You might want to refer to the documentation on cell arrays for more information. http://www.mathworks.com/help/matlab/cell-arrays.html

@Bill Tubbs maybe try nameArray(end+1) = {'name to be appended'}; should be a more efficient way of doing it

testFactor = 194225602
testStart = 3928
tic
mytest = [testStart];
for i = 1:100000
mytest = [mytest, testStart];
end
toc
tic
mytest = [testStart];
for i = 1:100000
mytest(end+1) = testStart;
end
toc
The result is :
2.024820
0.011121
list = [list, appendedNumber] is ridiculous.

Firstly you need to clarify whether you need to append strings or integer or string and integer
for only strings
name=input('What is your name? ', 's');
age=input('What is your age? ',"s");
hometown=input('What is your hometown? ', 's');
sport=input('What is your favorite sport? ', 's');
Temptex2=append(name,age,hometown,sport)
