so I have matrix and index value I want to get all the values in the row I tried Find & ismember but I didn't get all the values in row 2 matrix = [8 81 82;20 22 23; 3 31 32]; index = 2 find(ismember(matrix,inde
How to I find a value contained in a known index... Learn more about matrix, find, index, indices
hi, can anyone one help me if i have matrix A i want get index matrix for matrix A A=[9 5 1 6 5 7 8 4 11] for exmple The result A_index =11 12 13 21 22 23 31 32 33
These are the locations in the matrix in which the logical expression is true, in this case, any location greater than 12. Now the expressionA(A > 12) extracts the matrix elements corresponding to the nonzero values of the logical array. The output is always in the form of a column ...

FUN accepts % input X and returns a scalar function value F evaluated at X. X0 may be % a scalar, vector, or matrix. % % X = FMINCON(FUN,X0,A,B,Aeq,Beq) minimizes FUN subject to the linear % equalities Aeq*X = Beq as well as A*X <= B. (Set A=[] and B=[] if no...
第一种是Matrix Market (.mtx 格式),中间right hand side 是方程组 Ax=b 的右端项b。 第二种是 Harwell—Boeing 即(HB 格式) .rua 格式 。 注:mtx格式的矩阵就是通常的坐标存储方式,记录所有非零元的行和对应的列,而HB格式是新的存储方式,按照某种压缩原理,记录非零元,简单讲就是HB格式效率更高,同样...

Flip the outermost columns of matrix A, so that the first column becomes the last and the last column becomes the first. All other columns should be leftintact. Return the result in matrix B. If the input has one column, the output should be identical to the input. ...
