Before Dyuman Joshi kindly fixed it, the test suite for problem 60436 contained some syntax errors that made the problem unsolvable, so I took the liberty of fixing that. The task is the same as in that problem: given an integer in base 
(passed as a character array), convert it to base 
.
(passed as a character array), convert it to base .What's that you say? There are (well, were) other problems with the test suite of 60436 that I didn't fix here? Nah, can't be!

It looks like there is an issue with the assert statement. The assert function expects the first argument to be a condition that evaluates to a logical value (true or false). However, in this case, it’s comparing two character arrays directly, which is causing the error.
To fix this, you should use the isequal function to compare the output of switchbase with y_correct.
Please fix.
%%
x = '6428367';
b1 = 10;
b2 = 2;
y_correct = '11000100001011011001111';
assert(isequal(switchbase(x,b1,b2),y_correct))
%%
x = '6428367';
b1 = 9;
b2 = 2;
y_correct = '1101001000110110000100'; assert(isequal(switchbase(x,b1,b2),y_correct))
%%
x = '6428367';
b1 = 9;
b2 = 7;
y_correct = '41163052';
assert(isequal(switchbase(x,b1,b2),y_correct))
@George the broken test suite is on purpose. Your mission, should you choose to accept it, is to hack this problem such that you can still pass.
