Thank´s... What i need is something more complex, but i didn´t explain it... If i find 2 iqual elements like number 1, for example, what i need to do is connect the other elements in the same line. If i find 1 in to lines ([1 2] and [6 1]) what i need to do ...
如果find函数返回Empty matrix: 0-by-1，则表示矩阵a中不存在与max相等的元素。这可能是由于以下几种原因：矩阵a中没有最大值。矩阵a中存在多个最大值，但它们不恰好等于max。计算最大值时出现了舍入误差，导致最大值与预期值略有不同。为了避免这种情况，可以先确定矩阵a的最大值，然后再查找等于...
MATLAB® treats the array as a single column vector with each column appended to the bottom of the previous column. Thus, linear indexing numbers the elements in the columns from top to bottom, left to right. For example, consider a 3-by-3 matrix. You can reference the A(2,2) ...
Find number of zeros in a part of a matrixI need to find the number of zeros that are contained in a part of a matrix. For example if the matrix is [1 2 2 2 2 2 0 2 2 2 0 3 0 0 4 5 6 7 0 0 8] is there a fast way to get the number of zeros between the fifth ...
Open in MATLAB Online I have a large matrix with with multiple rows and a limited (but larger than 1) number of columns containing values between 0 and 9 and would like to find an efficient way to identify unique row-wise combinations and their indices to then build sums (some...
Solvers use the number of elements in, and size of, x0 to determine the number and size of variables that fun accepts. 'interior-point' algorithm — If the HonorBounds option is true (default), fmincon resets x0 components that are on or outside bounds lb or ub to values strictly ...
