SAGA.grid_calculus.4: Function Plotter

Generate a grid based on a functional expression. The function interpreter uses an formula expression parser that offers the following operators:<br/><table border="0"><tr><td><b>+</b></td><td>Addition</td></tr><tr><td><b>-</b></td><td>Subtraction</td></tr><tr><td><b>*</b></td><td>Multiplication</td></tr><tr><td><b>/</b></td><td>Division</td></tr><tr><td><b>abs(x)</b></td><td>Absolute Value</td></tr><tr><td><b>mod(x, y)</b></td><td>Returns the floating point remainder of x/y</td></tr><tr><td><b>int(x)</b></td><td>Returns the integer part of floating point value x</td></tr><tr><td><b>sqr(x)</b></td><td>Square</td></tr><tr><td><b>sqrt(x)</b></td><td>Square Root</td></tr><tr><td><b>exp(x)</b></td><td>Exponential</td></tr><tr><td><b>pow(x, y)</b></td><td>Returns x raised to the power of y</td></tr><tr><td><b>x ^ y</b></td><td>Returns x raised to the power of y</td></tr><tr><td><b>ln(x)</b></td><td>Natural Logarithm</td></tr><tr><td><b>log(x)</b></td><td>Base 10 Logarithm</td></tr><tr><td><b>pi()</b></td><td>Returns the value of Pi</td></tr><tr><td><b>sin(x)</b></td><td>Sine</td></tr><tr><td><b>cos(x)</b></td><td>Cosine</td></tr><tr><td><b>tan(x)</b></td><td>Tangent</td></tr><tr><td><b>asin(x)</b></td><td>Arcsine</td></tr><tr><td><b>acos(x)</b></td><td>Arccosine</td></tr><tr><td><b>atan(x)</b></td><td>Arctangent</td></tr><tr><td><b>atan2(x, y)</b></td><td>Arctangent of x/y</td></tr><tr><td><b>min(x, y)</b></td><td>Returns the minimum of values x and y</td></tr><tr><td><b>max(x, y)</b></td><td>Returns the maximum of values x and y</td></tr><tr><td><b>gt(x, y)</b></td><td>Returns true (1), if x is greater than y, else false (0)</td></tr><tr><td><b>x > y</b></td><td>Returns true (1), if x is greater than y, else false (0)</td></tr><tr><td><b>lt(x, y)</b></td><td>Returns true (1), if x is less than y, else false (0)</td></tr><tr><td><b>x < y</b></td><td>Returns true (1), if x is less than y, else false (0)</td></tr><tr><td><b>eq(x, y)</b></td><td>Returns true (1), if x equals y, else false (0)</td></tr><tr><td><b>x = y</b></td><td>Returns true (1), if x equals y, else false (0)</td></tr><tr><td><b>and(x, y)</b></td><td>Returns true (1), if both x and y are true (i.e. not 0)</td></tr><tr><td><b>or(x, y)</b></td><td>Returns true (1), if at least one of both x and y is true (i.e. not 0)</td></tr><tr><td><b>ifelse(c, x, y)</b></td><td>Returns x, if condition c is true (i.e. not 0), else y</td></tr><tr><td><b>rand_u(x, y)</b></td><td>Random number, uniform distribution with minimum x and maximum y</td></tr><tr><td><b>rand_g(x, y)</b></td><td>Random number, Gaussian distribution with mean x and standard deviation y</td></tr></table>
