### Test Suite

Test Status Code Input and Output
1   Fail
input = 1:3; output = {'1' '2' '3'}; assert(isequal(matrix2cell(input ),output)) assert(iscell(output),'output must be a cell')

Undefined function 'str' for input arguments of type 'double'. Error in matrix2cell (line 2) string = str(input); Error in Test1 (line 3) assert(isequal(matrix2cell(input ),output))

2   Fail
input = 0:5:8 output = {'0' '5'}; assert(isequal(matrix2cell(input ),output)) assert(iscell(output),'output must be a cell')

input = 0 5

Undefined function 'str' for input arguments of type 'double'. Error in matrix2cell (line 2) string = str(input); Error in Test2 (line 3) assert(isequal(matrix2cell(input ),output))

3   Fail
input =magic(3); output = {'8' '1' '6' '3' '5' '7' '4' '9' '2'} assert(isequal(matrix2cell(input ),output))

output = 3×3 cell array {'8'} {'1'} {'6'} {'3'} {'5'} {'7'} {'4'} {'9'} {'2'}

Undefined function 'str' for input arguments of type 'double'. Error in matrix2cell (line 2) string = str(input); Error in Test3 (line 5) assert(isequal(matrix2cell(input ),output))
