From the input box, hit the Enter key in your keyboard to get more input box, draw the right-low corner of the input box to get large. This calculator calculates numeric and string array with +, -, *, /, ^, and run JavaScript code.

Example :

x=matrix([[1,2],[3,4]]); x[1,1]
assign matrix to x, then x[1,1]. first [index] of x is 1

x=[[1,2],[3,4]]; x-i
assign array to x, then calculate x - i.

x=[[1,2],[3,4]]; det(x)
assign array to x, then calculate determinant of x

plot, e.g.
plot(sin(x),cos(x))
