Now we are going to practice matix functions!!!
```{r}
A = matrix(c(1,-1,2,0,3,4), nrow = 2, byrow = FALSE)
A
B = array(1:3, c(2,3))
B
is.matrix(A)
is.matrix(B)
A + B
A - B
B = t(B) # transpose
# prove of (A^T)T = A
A%*%B
{r cars}
summary(cars)
## Including Plots
You can also embed plots, for example:
{r pressure, echo=FALSE}
plot(pressure)
Note that the `echo = FALSE` parameter was added to the code chunk to prevent printing of the R code that generated the plot.
