How to make cell array same length after padding zeros

由 孤街醉人 提交于 2019-12-08 07:39:28
问题 This is data matrix having 2*159 cells In the data matrix so many columns ( 2 vectors) having different length . I want to pad zeros which have the minimum length. Number of zeros should be [max(length(Vector 1))-min(length(Vector 2))] Now I want add zeros in the cell which have minimum length. and want to make length equal in each column if column have same length than no problem. 回答1: n = max(max(cellfun(@(x)size(x,2),data))) cellfun(@(x)[x, zeros(1,n-numel(x))], data, 'uni', 0) The above

WPF: How can I find the source of an inherited property value

由 本秂侑毒 提交于 2019-12-08 03:49:38
问题 I've been working on a WPF-project that has a certain nick that I can't seem to grasp: there are a couple of controls that include other controls and are styled by a Style-definition in a Resource Dictionary. One of the inner controls is a Label. That Label has an inherited Padding of 5. The Label has no styling defined, let alone any padding. And it's indicated to be inherited, but I can't find where that Padding is coming from. So, my question is: how can I figure out where this value is

Ensure padding around markers on Google Maps for web [duplicate]

由 China☆狼群 提交于 2019-12-08 03:10:28
This question already has answers here : Google Maps API 3 fitBounds padding - ensure markers are not obscured by overlaid controls (7 answers) Closed 3 years ago . I have a full screen Google map with HTML/CSS toolbars overlaid on the map, and a set of map markers. Is there a way to ensure there is enough padding between the markers and the edges of the map, so that no markers are obscured by the toolbars? ( Codepen in case the code below doesn't work) function initMap() { var map = new google.maps.Map(document.getElementById('map'), { draggable: true, streetViewControl: false, zoomControl:

how to get the size of the padding at the end of a class

由 倖福魔咒の 提交于 2019-12-08 03:02:26
I have a class A like this: struct V { virtual void f() = 0; }; struct A { int data; }; struct B : public A , public V { void f() override {} }; MSVC gives me sizeof(A) == 4 and sizeof(B) == 16 on a 64 bit build instead of 12 ( sizeof(void*) + sizeof(A) ) - so there is a 4 byte padding. Is there a way to get that padding? perhaps with some trait? The reason I need this is to do an assert like this: static_assert(sizeof(B) == sizeof(A) + std::is_polymorphic<camera>::value * sizeof(void*)); Meaning that I want to ensure that all data is in the base class, but B should be able to be polymorphic

问题 I have a select element where I enable users to choose the classification and description. In chrome browser only, I have an extra padding which I am not able remove with padding:0 or with other css tags. Screen from Chrome However, the same element in other browsers does not have any padding. See example screen from firefox.Screen from Firefox Any idea why this can be the case? Thank you 回答1: This may help reset all the browser-specific styling for select elements: -webkit-appearance:none;

来自于： http://nec.netease.com/standard/html-email.html 邮件环境 邮件内容所在上下文或者说所在外部容器（以下简称环境）都是由邮箱服务商决定的，这就要求邮件内容需要在任何一种情况下都要正确显示。 这些环境可能是以下某几种情况： 可能是个iframe，你的内容是被放在body里面的；可能只是个div，你的内容就被放在这个div里面。 可能邮箱自身设置了些css，他可能对你产生未知的影响。 可能根本没有申明doctype，即使申明了，也不是你想要的doctype。 避免被嵌套在不正确的容器里 惑：因为容器可能是body或div，所以，我们邮件内容不应该是一个完整的html。 解：所以邮件内容应该是以div为根节点的html片段。 避免css冲突或被覆盖 惑：因为环境中可能已经设置了css，比如一些reset、一些.class。 解：所以我们只能使用行内style来确保我们的效果，并且在内容根节点上设置基础style，并且尽量使用div、span等无语义标签。 1 2 3 4 5 6 7 8 9 10 11 12 13 14 <!-- 根节点 --> < div style = "width:600px;text-align:left;color:#000;font:normal 12px/15px arial,simsun

Openssl PKCS#5/PKCS#7 padding

由 醉酒当歌 提交于 2019-12-07 23:49:10
问题 I was wondering how openssl handles a message that is dividable by 8 bytes when using AES-128-CBC. How can openssl detect that there is no padding (PKCS#5/PKCS#7) to be removed? Especially when the message ends in a character with an ASCII code less than or equal to 8. I hope my question is clear. Thanks 回答1: Well the answer is that padding is always added, even if the data can be divided by the block size. Thus a 8 byte string will be padded with 8 bytes (with ASCII code 8). 来源： https:/

Spark map与flatmap区别

案例说明1： 步骤一：将 测试 数据放到hdfs上面 hadoopdfs -put data1/test1.txt /tmp/test1.txt 该测试数据有两行文本： 步骤二：在 Spark 中创建一个RDD来读取hdfs文件/tmp/test1.txt 步骤三：查看map函数的返回值 得到map函数返回的RDD: 查看map函数的返回值——文件中的每一行数据返回了一个数组对象 步骤四：查看flatMap函数的返回值 得到flatMap函数返回的RDD: 查看flatMap函数的返回值——文件中的所有行数据仅返回了一个数组对象 总结： - Spark 中 map函数会对每一条输入进行指定的操作，然后为每一条输入返回一个对象； - 而flatMap函数则是两个操作的集合——正是“先映射后扁平化”： 操作1：同map函数一样：对每一条输入进行指定的操作，然后为每一条输入返回一个对象 操作2：最后将所有对象合并为一个对象 案例说明2： 假设存在如下文件： <code class="hljs ruby has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source
