I have a 2x56 matrix of values, and I need to take the weighted average of every individual row and store it in a 1x56 matrix. One row weighs 1/3 and the other row weighs 2/3. How do I go about doing this without the use of another vector?

'absolute'Display the total number of observations in each cell. 'column-normalized'Normalize each cell value by the number of observations that has the same predicted class. 'row-normalized'Normalize each cell value by the number of observations that has the same true class. ...
Before R2021a, use commas to separate each name and value, and enclose Name in quotes. Example: dA = decomposition(A,'qr','CheckCondition',false) performs a QR decomposition of A and turns off warnings about the condition of the coefficient matrix when it is used to solve a linear syste...
Vq= interp2(V)returns the interpolated values on a refined grid formed by dividing the interval between sample values once in each dimension. Vq= interp2(V,k)returns the interpolated values on a refined grid formed by repeatedly halving the intervalsktimes in each dimension. This results in2^...
How to obtain trend p-values for each cell of a matrix?You are right that regstats returns a structure, but it contains numeric values that you can assign into a matrix. For example, something like this:
In Matlab, the if statement is a very common control statement that is used to execute different command codes depending on the condition. If satisfied, proceed to another command given. When there are nested ifs, each if must match a corresponding end. When using else if or else nested ins...
How to choose one value for each row and column in a matrix so that the sum of values in the matrix is minimizedHi Matt, Thanks for your question. You can only make one selection per row, so once a selection has been made in a row none o...
Mdl = fitctree(Tbl,Y) returns a fitted binary classification decision tree based on the input variables contained in the table Tbl and output in vector Y.Mdl = fitctree(X,Y) returns a fitted binary classification decision tree based on the input variables contained in matrix X and output Y....
The coding design is a matrix whose elements direct which classes are trained by each binary learner, that is, how the multiclass problem is reduced to a series of binary problems. Each row of the coding design corresponds to a distinct class, and each column corresponds to a binary learner...
