I have this for loop that's supposed to divide each element of P by two, then I graph P but it's always double what it needs to be. N is 120 and P is a 1x120 array so it's not an indexing problem. When I isolate my P array in another script and divide each element by 2...
B is a denominator and it can be a scalar , vector or matrix.Let us see few examples.Example 1In the example below we are going to divide matrix A with matrix B.Open Compiler A = [7, 8; 5, 6] B = [3, 2; 1, 4] X = A / B ...
MATLAB has many built-in functions that generate outputs of arbitrary dimensions. Sometimes it is useful to produce an array of a given size that you will later populate with meaningful data. Try the following commands to generate two-dimensional matrices of all ones and all zeros: >>z=ones(...
Ifstris a string array or cell array of character vectors, and has multiple elements, then each element must be divisible into the same number of substrings. Ifstris a string scalar or character vector, thennewStris anN-by-1string array or cell array of character vectors, whereNis the numbe...

MATLAB iscase-sensitive. Variable names can be of any length, however, MATLAB uses only first N characters, where N is given by the functionnamelengthmax. Saving Your Work Thesavecommand is used for saving all the variables in the workspace, as a file with .mat extension, in the current...
multidimensional array; however, we can set it to other dimensions by defining the dimension number as the third argument in thequantile()function. The fourth syntax is used to set the method used to compute the quantiles, which is set to theexactmethod by default, but we can also set it...
Calculate the speedup by computing the ratio between the computation time of a single worker and the computation time of each maximum number of workers. To calculate the efficiency of parallelizing the tasks, divide the ideal speedup by the calculated speedup. ...
Convenience constructor The array constructor takes (nested) Python sequences as initializers. As in, array([[1,2,3],[4,5,6]]). The matrix constructor additionally takes a convenient string initializer. As in matrix("[1 2 3; 4 5 6]").There are pros and cons to using both:...
Interpolated values, returned as a real or complex scalar, vector, or array. The size and shape of Vq depends on the syntax you use and, in some cases, the size and value of the input arguments. SyntaxesSpecial ConditionsSize of VqExample interp3(X,Y,Z,V,Xq,Yq,Zq) interp3(V,Xq,...
