Test Status Code Input and Output
1   Fail
u = [0.5 0.5 0];; v = [1 0 0]; angle_in_degrees = vector2angle(u,v) assert(strcmp(num2str(angle_in_degrees),'45'))

Error in solution: Line: 2 Column: 59 Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.

2   Fail
u = [0 0 1]; v = [1 0 0]; angle_in_degrees = vector2angle(u,v) assert(strcmp(num2str(angle_in_degrees),'90'))

Error in solution: Line: 2 Column: 59 Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.

3   Fail
u = [0 0.8 1]; v = [1 0.3 0]; angle_in_degrees = vector2angle(u,v) assert(strcmp(num2str(round(angle_in_degrees)),'80'))
