Basically im trying to write my fist line of code, in matlab, to the given formula: |G (jw) |= 1/√ (R^2+ (wL- 1/wC)^2 ) Now, im not sure how to get the 1/wC term as I do not know how to divide in matlab. also, how do I get the ^2? All I want is the general form as an answer. Divide arguments element-wise. Parameters: x1 array_like. Dividend array. x2 array_like. Divisor array. If x1.shape!= x2.shape, they must be broadcastable to a common shape (which becomes the shape of the output). out ndarray, …The natural logarithm function in MATLAB is log(). To calculate the natural logarithm of a scalar, vector or array, A, enter log(A). Log(A) calculates the natural logarithm of each element of A when A is a vector or array.Each value of this matrix is equal to a formula as such: B (i,1) = log ( (S (:,:,1)/S0)/b) Where S (x,y,z) is a 115x94x64 matrix, S0 is a 115x94 matrix, and b is a constant value.

C = A.*B multiplies arrays A and B by multiplying corresponding elements. The sizes of A and B must be the same or be compatible. If the sizes of A and B are compatible, then the two arrays implicitly expand to match each other. For example, if one of A or B is a scalar, then the scalar is combined with each element of the other array.22. Link. There are two principal ways to create vectors in MATLAB. One is the colon (:) operator, and the other is the linspace function. The principal difference is that with the colon operator, you define the interval between successive elements and let the length of the resulting vector vary, and in linspace, you define the length of the ...This example shows how perform right-array division on a 3-by-3 magic square of fi objects. Each element of the 3-by-3 magic square is divided by the corresponding element in the 3-by-3 input array b.

Real and imaginary components, phase angles. In MATLAB ®, i and j represent the basic imaginary unit. You can use them to create complex numbers such as 2i+5. You can also determine the real and imaginary parts of complex numbers and compute other common values such as phase and angle.Special Matrices. MATLAB also provides functions to generate specific types of matrices. Some commonly used functions include: zeros(m, n): Creates an m-by-n matrix filled with zeros. ones(m, n): Creates an m-by-n matrix filled with ones. eye(m, n): Creates an m-by-n identity matrix (ones on the diagonal and zeros elsewhere). For example:MATLAB can be used to perform shifting of signals. A signal can be delayed as well as advanced. The basic idea is to add the shift value to indices and thereby plotting the signal. The following is a program to delay or advance a signal x(n). The shift value is decided at the run time. Eg:How to divide a matrix by a number .
