In general the data is in the following format: Input data format For functions with two varibles (+, -, *, and /), the input data should be in two columns as (x1, x2). The result of the operations are x1 + x2, x1 - x2, x1 * x2, and x1 / x2, respectively. For functions with one varible (i.e., cos( x ) ), the input data can be in one column or multiple columns. Results are displayed in a matrix form if the input data is in a matrix form. For funtions with array variable (i.e, max( x ), std( x )), the input data in each column is an array. Functions +   plus: x1 + x2 -   minus: x1 - x2 *   time: x1 * x2 /   divide: x1 / x2 abs   absolute value: |x| acos   arc cosine: acos(x) asin    arc sine: asin(x) atan    arc tangent: atan(x) atan2(x2, x1)    converts rectangular coordinates (x1, x2) to polar (r, theta) ceil    the smallest integer value that is not less than x: ceil(x) cos    the trigonometric cosine: cos(x) E    Euler's number e exp    Exponential function: exp(x) floor   the largest integer value that is not greater than x: floor(x) inverse   inverse: 1/x mod(x, a)    the remainder of x - n * a ln    the natural logarithm (base e): loge(x) log10    the logarithm (base 10): log10(x) loga    the logarithm (base a): loga(x) max    the greatest value in an array: max(x) mean    mean value of an array: mean(x) min    the smallest value in an array: min(x) PI    the constant Pi power    x to the a-th power: xa random    random number between 0 and 1 round    round to the coloses integer: round(x) round2    round to the a-th decimal point: round(x, a) std    standard deviation of an array: std(x) stdN-1    bias-corrected standard deviation of an array: stdN-1(x) sin    the trigonometric sine: sin(x) sqrt    positive square root: sqrt(x) sum    sum of an array: sum(x) tan    the trigonometric tangent: tan(x) toDegrees    converts an angle measured in radians to degrees toRadians    converts an angle measured in degrees to radians var    variance of an array: var(x) Thanks for using our software!
