Step 2:Then, we use a find value in array with proper syntax to find the nonzero element values. Examples of Matlab find value in array Given below are the examples of Matlab find value in array: Example #1 Let
To find array elements that meet a condition, usefindin conjunction with a relational expression. For example,find(X<5)returns the linear indices to the elements inXthat are less than5. To directly find the elements inXthat satisfy the conditionX<5, useX(X<5). Avoid function calls likeX...
Find the nonzero elements in a 4-by-2-by-3 array. Specify two outputs, row and col, to return the row and column subscripts of the nonzero elements. When the input is a multidimensional array (N > 2), find returns col as a linear index over the N-1 trailing dimensions of X. Ge...
Set the initial value to 3000 for the"wheat-onion"and"wheat-lentil"crops that are planted in any dry condition and are plowed traditionally. [idxLand, idxCrop, idxPlough] = findindex(xcrop, ["dry-good","dry-poor"],...["wheat-onion","wheat-lentil"],"tradition"); x0.xcrop(idxLand...

Index array, returned as a vector, matrix, or multidimensional array.Iis the same size asB. If the output arrayBcontains repeated elements, then the order of their indices inImatches the order in which they appear in the input array.

SIFT是由UBC(university of British Column)的教授David Lowe于1999年提出、并在2004年得以完善的一种检测图像关键点(key points , 或者称为图像的interest points(兴趣点) ), 并对关键点提取其局部尺度不变特征的描绘子, 采用这个描绘子进行用于对两幅相关的图像进行匹配(matching)。
