Optionally upload a CSV of data that will be available as data frame "df":

# Solve the following system of equations: # 5x + 3y = 19 # 2x + 6y = 22 a <- matrix(c(5, 3, 2, 6), nrow=2, ncol=2, byrow=TRUE) b <- matrix(c(19, 22), nrow=2) a b a[2, 1] # example of how to access a single element a[2, ] # access a row a[, 2] # access a column solve(a, b) # other matrix operations, transpose, inverse, eigenvalues/vectors t(a) solve(a) eigen(a)
