Barypolyint2

polyint2(x1, x2, y, t1, t2)

x1, x2 are vectors of length of m and n, y is a n-by-m matrix, t1 and t2 are scalars

Return a value interpolated from y = y(x1, x2) data set for (t1, t2) data point

Input

Output

x1 = linspace(0, PI/5.0, 6)

x2 = linspace(0, 4, 5)

y= transpose(exp(x2)) * sin(x1)
