Hello, I have two matrices: Y, which is a 2462x220 matrix Y_dif, which has the same dimensions Basicaly, I want to add a submatrix within Y_dif to a submatrix of Y. More specifically: For rows 505:560 and columns 46:50 in matrix Y I want to ...
I would simply like to add two matrices together, element-wise, ignoring the NaNs. I realize one solution is to replace NaNs with zeros but I have some reported zeros that I want to be able to later identify. A solution to that is to set any rea...
In contrast, the .* operator performs elementwise multiplication and allows you to multiply the corresponding elements of two equally sized arrays. z = [3 4] .* [10 20] z = 30 80 奇奇怪怪的运算: https://www.mathworks.com/help/matlab/matlab_prog/compatible-array-sizes-for-basic-operation...
The operators ./ and .^ in the calculation of BMI indicate element-wise division and exponentiation, respectively. Display the first five rows of the table T. Get head(T,5) LastName Age SelfAssessedHealthStatus Smoker Height Weight Systolic Diastolic BloodPressure BMI ___ ___ ___ __...
Use element-wise operators for the best performance and to avoid a warning message. For example, usex.*yinstead ofx*y. For more information, seeArray vs. Matrix Operations. When you zoom in on the chart,fplotreplots the data, which can reveal hidden details. ...
In this case, the matrix, say A, acts a column-vector containing the elements of A arranged column-wise. Thus, for a 3×3 matrix, A(4) is equivalent to A(1,2). The MatLab functions, sub2ind() and ind2sub(), translate between two “subscripts”, i and j, and a vector “index...
With NumPy arrays, you can do things like inner and outer products, transposition, and element-wise operations. NumPy also contains a number of useful methods for reading text and binary data files, fitting polynomial functions, many mathematical functions (sine, cosine, square root, and so on)...
To vary a single element of a matrix or array variable, in theAdd new parameter by indexing/expression with existing onefield, enter an expression that resolves to a numeric scalar value and pressEnterkey. For example, ifAis a vector, enterA(3)to specify the third entry inA. IfAis a st...
