Expected Returns

Wigner3j(j1,j2,j,m1,m2,m) returns the Wigner 3j-symbol, where j1, j2, j, m1, m2, and m are half-integers. Physically, the Wigner 3j-symbol is closely related to the Clebsch-Gordon coefficient , the square of which is the probability that a system of two particles with angular momentum j1 and j2...

sometimes, you want an image that contains text, instead of manually drawing 1s and 0s , this functino takes a string and returns a matrix of 1s and 0s in the form of that string. (tjhe matrix is rectangular the text string is represented as being painted by 1s)
