To calculate a double integral using the trapz function in MATLAB, you can first create a grid of points for the two variables you are integrating over. Then, evaluate the function you are integrating at these points to create a matrix of function values. Finally, use the trapz function twice - once along one dimension and then along the other dimension - to compute the double integral.

How do you mix PHP with a string inside CodeIgniter function?

You must start with double quotes to get expanded variables, then escape nested ones with backslash <?php echo form_radio($data['filename'], 0, '', "class="uniform" id="$data[ids]""); Or use single quotes inside double <?php echo form_radio($data['filename'], 0, '', "class='uniform' id='$data[ids]'"); Notice you don't need to quote single dimensional array indexes inside the square braces if inside double quotes


What is the implementation of the distance function in C for calculating the distance between two points in a program?

To implement the distance function in C for calculating the distance between two points in a program, you can use the formula for Euclidean distance: double distance sqrt(pow((x2 - x1), 2) pow((y2 - y1), 2)); This formula calculates the distance between two points (x1, y1) and (x2, y2) in a Cartesian coordinate system.


How can I convert a float to a double in Java?

To convert a float to a double in Java, you can simply assign the float value to a double variable. Java will automatically perform the conversion for you. Here's an example: java float floatValue 10.5f; double doubleValue floatValue; In this example, the float value 10.5f is assigned to the double variable doubleValue, which will now hold the converted double value.


How can I declare a double precision variable in Fortran?

To declare a double precision variable in Fortran, you can use the "real(kind8)" declaration. This specifies that the variable should be of double precision, which is typically 8 bytes in size.

Is integration a way of calculating the volume of the same function equation with an additional dimension or is it always completely new volume rotated about an axis ie a circle to a sphere?

Geometrically the definite integral from a to b is the area under the curve and the double integral is the volume under the surface. So just taking the integral of a function does not yield the volume of the solid made by rotating it around an axis. An integral is only a solid of revolution if you take an infinite sum of infinitesimally small cylinders that is the disk method or you do the same with shells.


In line integral and surface integral you need a vector function f but integrand were actually scalar function why?

You don't need a vector function. A scalar function over a line or surface, and often this is easier than a line or surface integral of a vector function.When you do a line or surface integral of a vector function, you're really integrating the dot product of the vector function with the tangent to the line (for a line integral), or integrating the dot product of the vector function with the normal to a surface (for a surface integral). In both cases, the result of a dot product is just a scalar that you end up integrating over the line or surface. When you do a line or surface or integral of a scalar function you're halfway there already because you're skipping the vector dot product!Line integrals:If you think about it, the usual integration a function f(x) from a to b is equivalent to the line integral of the scalar function f(x) in the xy plane (f simply doesn't depend on y) along the straight line segment from (a, 0) to (b, 0). A more general line integral just extends this idea to an integral over a non-straight line.To do a general line integral of a scalar function f(x) (where x is a vector x = ) along a curve, you must parameterize the curve. Typically the parameterization is denoted by a vector-valued function, r(t) = , of a single parameter, t. Typically bounds would be given for t, such as a

What is the difference between triple integral and volume integral?

While I searching for the answer to this question, I totally confused. Atlast I reach in one thing that we may compute some volume integrals by using double integral but to evaluate a triple integral we should go through all the three integrals.


What is the c plus plus program to calculate the area of a circle using function overloading?

Function overloading is used when you want to re-use the same function name with different argument types or a different number of arguments. Calculating the area of a circle isn't the sort of function that requires overloading since the only argument you need is the radius. double area_of_circle (const double radius) { const double pi=4*atan(1); return pi*radius*radius; }
