Youcan square a matrix if it has the same number of rows and columns. This means you can square an nxn matrix, such as a 1x1, 2x2, or 3x3 matrix. If the number of rows is different from the number of columns, then you cannot square the matrix. We can add and subtract matrices, but sometimes we might want to multiply a matrix.
therows of the augmented matrix. Thus, multiplying a row of a matrix by a number k means multiplying every entry of the row by k. Adding one row to another row means adding each entry of that row to the corresponding entry of the other row. Subtracting two rows is done similarly. Note that we regard two
Thusto undo matrix multiplication, you need to multiply by the inverse matrix. It is thus a pretty fundamental operation. One early application for inverse matrices is to solve systems of linear equations. You can express the system as a matrix equation AX=B, then solve it by multiplying by the inverse of the coefficient matrix to get X = A^(-1)*B
tablesof integer configurations for small 2X2 tables, for which the probabilities- are equal to, or less than, conventional significance levels. Bennett and Nakamura (1963) have published similar tabula-tions for 2X3 tables, and have also examined (1964) the power func-tion of the exact test of 2X3 tables. Kullback et al. (1962) have
