### Test Suite

Test Status Code Input and Output
1   Fail
x = 1; m = 197; n = 535; y_correct = ones(m, n); assert(isequal(repl_mat(x, m, n),y_correct))

Assertion failed.

2   Fail
x = 0; m = 458; n = 535; y_correct = zeros(m, n); assert(isequal(repl_mat(x, m, n),y_correct))

Assertion failed.

3   Fail
x = 2; m = 1; n = 1; y_correct = 2; assert(isequal(repl_mat(x, m, n),y_correct))

Assertion failed.

4   Fail
x = -1; m = 1; n = 2; y_correct = [-1 -1]; assert(isequal(repl_mat(x, m, n),y_correct))

Error using repelem Replication factors must be nonnegative integer-valued scalars or vectors. Error in repl_mat (line 2) y = repelem(m,n,x); Error in Test4 (line 5) assert(isequal(repl_mat(x, m, n),y_correct))

5   Fail
x = 1.5; m = 2; n = 2; y_correct = [1.5 1.5; 1.5 1.5]; assert(isequal(repl_mat(x, m, n),y_correct))

Error using repelem Replication factors must be nonnegative integer-valued scalars or vectors. Error in repl_mat (line 2) y = repelem(m,n,x); Error in Test5 (line 5) assert(isequal(repl_mat(x, m, n),y_correct))

6   Fail
x = '1'; m = 1; n = 3; y_correct = ['1' '1' '1']; assert(isequal(repl_mat(x, m, n),y_correct))

Error using repelem Replication factors must be numeric. Error in repl_mat (line 2) y = repelem(m,n,x); Error in Test6 (line 5) assert(isequal(repl_mat(x, m, n),y_correct))
