Hello all,

I'm trying to draw a cube, however need help figuring out what algorithm would be.

So far I have:

function [ cubic ] = Cube( sideLength )
%UNTITLED12 Summary of this function goes here
%   Detailed explanation goes here
for i = 1:sideLength
    cubic = sideLength 
    fprintf('+', sideLength)
end

I need to write a function that will take one integer and print it like this:

a. Example 1.
>> cube(2)
+----+
|\ \
| +----+
+ | |
\| |
 +----+
b. Example 2.
>> cube(4)
+--------+
|\ \
| \ \
| +--------+
| | |
+ | |
\ | |
 \| |
 +--------+

The question asks for:

3. Draw a cube. Write a function (cube) that takes a single integer argument (side length of cube) and draws a 2-dimensional representation of a cube. The cube should be drawn using + for corners, - for horizontal lines, | for vertical lines, and \ for diagonals. A cube of size

Yes but you surely tried more than this loop that does not even use FPRINTF correctly.

Show us that you made some effort.

Try to split the approach in a series of small steps:

Am I able to print just a '+'? Yes/no, if no I read the doc of FPRINTF, look for examples online, etc.
Am I able to repeat '-' a given number of times? Yes/no, if no I google repeat elements in MATLAB, I read about REPELEM or REPMAT and train.
Using this, am I able to print a horizontal edge without the '+'? ...
.. and what about one with the '+'?
Using this, am I able to print a row of vertical edges of just a square for starting? ...
...
