How do concatenation and indexing differ for cells and arrays in MATLAB?

阅读更多关于 How do concatenation and indexing differ for cells and arrays in MATLAB?

问题 I am a little confused about the usage of cells and arrays in MATLAB and would like some clarification on a few points. Here are my observations: An array can dynamically adjust its own memory to allow for a dynamic number of elements, while cells seem to not act in the same way: a=[]; a=[a 1]; b={}; b={b 1}; Several elements can be retrieved from cells, but it doesn't seem like they can be from arrays: a={'1' '2'}; figure; plot(...); hold on; plot(...); legend(a{1:2}); b=['1' '2']; figure;

Find the first empty cell in the same column/row

阅读更多关于 Find the first empty cell in the same column/row

I am trying to work out a formula that will give me the row number of the first empty cell in a column. Currently I am using: =MATCH(TRUE, INDEX(ISBLANK(A:A), 0, 0), 0) This works fine, unless the formula is put in the same column as the column I am searching in, in which case it does some sort of circular reference or something. Is there a formula I can use instead which will work when placed in the same column as it searches in? Another way to do it =MIN(IF(A2:A6="",ROW(A2:A6))) you have to press CTRL+SHIFT+ENTER The difference is that this will give you the Row number of the first empty

基于循环神经网络实现基于字符的语言模型（char-level RNN Language Model）-tensorflow实现

阅读更多关于基于循环神经网络实现基于字符的语言模型（char-level RNN Language Model）-tensorflow实现

前面几章介绍了卷积神经网络在自然语言处理中的应用，这是因为卷积神经网络便于理解并且易上手编程，大多教程（比如tensorflow的官方文档就先CNN再RNN）。但RNN的原理决定了它先天就适合做自然语言处理方向的问题（如语言模型，语音识别，文本翻译等等）。因此接下来一段时间应该会着重研究RNN，LSTM，Attention等在NLP的应用及其tensorflow实现。在介绍本篇文章之前，先推荐几篇学习内容：语言模型部分： 1、 CS224d 第四篇notes ，首先讲语言模型的问题，然后推导了RNN、biRNN和LSTM。比99%的中文博客要靠谱。 2、 language model and word2vec ，前半部分是语言模型，后半部分介绍了Skip-gram等模型，并引入word2vec。 RNN和LSTM部分： 1、 The Unreasonable Effectiveness of Recurrent Neural Networks 该文主要介绍了RNN在NLP中的应用，很直观。 2、 Understanding LSTM Networks LSTM过程中很完美的公式，相信看一遍就能记住。 3、 2的中文版对自己英文不自信的同学可以看这个译文。本篇文章实现基于字符的RNN语言模型，源自于 Understanding LSTM Networks ，在该篇文章中也附有

As you read this essay, you understand each word based on your understanding of previous words. You don’t throw everything away and start thinking from scratch again. Your thoughts have persistence. Traditional neural networks can’t do this, and it seems like a major shortcoming. For example, imagine you want to classify what kind of event is happening at every point in a movie.

问题 I have created gridview with customer adapter. To give each cell border, I have placed them in two layouts. The first layout has black bg and second layout has white bg and contents. and I have given the parent layout 1dp padding, which given a border look but the problem is that when two cells meet vertically, their border size becomes 2dp i.e. one cell's bottom border merges into other cell's top border. But I like to create border as in given image Here is code of my current cell's xml

excel cell coloring

I am using c# to color particular cells of excel file. I am using: Application excel = new Application(); Workbook wb = excel.Workbooks.Open(destPath); Worksheet ws = wb.Worksheets[1]; ws.get_Range(ws.Cells[row, clmn]).Cells.Interior.Color = 36; ...to color cells, but this is not working. Can anyone help me out? Try something like that ws.Cells[row, clmn].Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red) Cells[row, clmn] is a range so you don't need to call get_Range() and there is a enum that you can use for colors. ws.Cells[row, clmn].Interior.Color = XlRgbColor

I was hoping for cell.Add(myImage) But I assume it is not that easy. /Stefan Thanks for your input doitgood The following

SSRS Field Expression to change the background color of the Cell

阅读更多关于 SSRS Field Expression to change the background color of the Cell

I'm trying to write a field expression for a Cell in my report where I have to change the background color of the cell depending on the string value in the cell. Ex: if the column has a value 'Approved' in it, the cell should show a green background color. I tried the following: = IIF(fields!column.value = "Approved", "Green") and = IIF(Fields!column.Value, "Approved", "Green") Neither works.. I know i'm missing something in the syntax.. Probably I'm not refering green to the back ground color in the syntax. Please help! Hopdizzle The problem with IIF(Fields!column.Value = "Approved", "Green")
