I have an array (1024x1024). For each element, I want to find the difference between that element and all 8 neighboring elements. From there, I want to take the max difference and write it to a new array in that element's position. ...
If you do not specify the dimension, then the default is the first array dimension whose size does not equal 1. Consider a two-dimensional p-by-m input array, A: diff(A,1,1) works on successive elements in the columns of A and returns a (p-1)-by-m difference matrix. diff(A,1...
Rather than do everything by hand, I figured it would be easier to throw them in matlab and have it calculate it. Right now, I'm at a point where I have calculated theta values in an array (11,1). For the equation I am using, I need to find the difference be...
diff(A,1,2)works on successive elements in the rows ofAand returns a p-by-(m-1) difference matrix. Data Types:double|single|int8|int16|int32|int64|uint8|uint16|uint32|uint64 Output Arguments collapse all Y— Difference array
Difference image, returned as a numeric array.Zhas the same class and size asXandY. IfXandYare integer arrays, thenimabsdifftruncates elements in the output that exceed the range of the integer type. Extended Capabilities C/C++ Code Generation ...

Matlab diff function is used to find the difference between 2 adjacent elements in a series or array. In the case of matrices, it is used to find the adjacent rows or columns’ difference depending upon the dimension passed as the argument. By default, this function calculates the 1st order...
max:Largest elements in array,寻找最大值。 max(a) :寻找数组a中的最大元素。 max(a,b):返回a和b中的最大值,分一下情况: >> a=magic(3) a = 8 1 6 3 5 7 4 9 2 >> max(a,2) ans = 8 2 6 3 5 7 4 9 2 如果a为矩阵或向量,b为一个数,则max会将a中所有小于b的数替换成b。
1、Observe the difference between(注意以下两者的差异) 1)a=10 2)b=10; 2、“;”at the end of a command suppresses output to the terminal(semicolon用于在命令的末尾抑制结果的输出,即不显示运算结果) 3、 \uparrow display previous commands(方向键\uparrow显示之前的命令) 五、Some Functions(小技巧)...
