Department of Arthritis andImmunology, Oklahoma Medical Research Foundation, Oklahoma City, OK, USA 73104. We introduce a novel Matlab toolbox for microarray data analysis. This toolbox uses normalization based upon a normally distributed background and differential gene expression based on 5 statistical measures. The objects in this toolbox are open source and can be implemented to suit your application. AVAILABILITY: MDAT v1.0 is a Matlab toolbox and requires Matlab to run.

Matlab如何添加新的工具箱经验总结
Matlab如何添加新的工具箱经验总结Matlab如何添加新的工具箱-经验总结最近在学习遗传算法与免疫算法,所以涉及到matlab的工具箱的应用,尤其gads 工具箱,所以在网上下载了一些工具箱,但是不会用,在网上找了点资料,留着以后也可以用。
1,我是单独下载的工具箱,把新的工具箱拷贝到某个目录(我的是C:\Program Files\MATLAB\R2010\toolbox)。
注意:你要是添加的很多个m文件,那就把这些m文件直接拷到再下一层你想要的工具箱的文件夹里例如,我要添加的是遗传工具箱,在刚才的文件夹下我已经有gads(遗传工具箱)文件夹了,但有的m文件还没有,我就把新的m 文件统统拷到C:\Program Files\MATLAB\R2010\toolbox\gads目录下了如果你连某工具箱(你打算添加的)的文件夹都没有,那就把文件夹和文件一起拷到C:\Program Files\MATLAB\R2010\toolbox下。
先把工具箱保存到MATLAB安装目录的根目录下面,然后运行matlab---->file---->set path---->add folder 然后把你的工具箱文件夹添加进去就可以了2 在matlab的菜单file下面的set path把它(C:\ProgramFiles\MATLAB\R2010\toolbox\gads)加上。
3 把路径加进去后在file→Preferences→General的Toolbox Path Caching 里点击update Toolbox Path Cache更新一下。
记得一定要更新!我就是没更新,所以添加了路径,一运行还是不行。
后来更新了才行。
4 用which newtoolbox_command.m来检验是否可以访问。
如果能够显示新设置的路径,则表明该工具箱可以使用了。
这个我也不知道怎么用。
怎么检验?在命令窗口输入whichnewtoolbox_command.m?还是打开whichnewtoolbox_command.m文件(我搜索了,没找到这个文件啊)我一直没搞懂。

matlab常见的错误提示及其解决方法
matlab常见的错误提示及其解决方法(2011-07-23 09:08:09)分类:matlab学习标签:matlab常见错误原因解决方法it今天在百度知道上收到求助,说想知道matlab常见错误。
个人虽然也学了点matlab皮毛,并且碰过不少问题,但从没有认真总结过常见的错误。
于是上网搜索一番,整理出常见的错误,当前以整理出的内容如下,不足之处待以后补充,也期待看到此篇博文的朋友帮忙指出不足。
1.Undefined function or variable "U"中文解释:函数或变量 U 没有定义出错原因:函数或变量 U 没有定义解决办法:仔细检查错误所指向的位置,寻找没有定义的函数或者变量,加以定义。
2.Unexpected MATLAB expression.中文解释:不规范的matlab表达式出错原因:少了运算符号,或者括号等情况解决办法:仔细检查错误所指向的位置,检查是否少了乘号,或者逗号、分号、括号等。
3.Subscript indices must either be real positive integers or logicals中文解释:下标索引必须是正整数类型或者逻辑类型出错原因:在访问矩阵(包括向量、二维矩阵、多维数组,下同)的过程中,下标索引要么从 0 开始,要么出现了负数。
注:matlab 的语法规定矩阵的索引从 1 开始,这与 C 等编程语言的习惯不一样。
解决办法:自己调试一下程序,把下标为 0 或者负数的地方修正。
4.Matrix dimensions must agree中文解释:矩阵的维数必须一致出错原因:这是由于运算符(= + - / * 等)两边的运算对象维数不匹配造成的,典型的出错原因是错用了矩阵运算符。
matlab 通过“.”来区分矩阵运算和元素运算。
解决办法:自己调试一下程序,保证运算符两边的运算对象维数一致。
5.Function definitions are not permitted at the prompt or in scripts中文解释:不能在命令窗口或者脚本文件中定义函数出错原因:一旦在命令窗口写 function c = myPlus(a,b),此错误就会出现,因为函数只能定义在 m 文件中。

关于matlab 标定工具箱的使用
关于matlab 标定工具箱的使用在/bouguetj/calib_doc/提供了一个很好的matlab标定工具箱,但在使用中我发现由于原工具箱的目录设置问题,常常在第一步卡住程序无法运行,因此我对程序进行了更改,更改后的标定工具箱使用步骤如下:1> 读入图像数据启动matlab并将当前工作目录设置为包含待标定图像的目录(即包含代表顶图像的文件夹)打开calib_gui.m文件,运行此程序,弹出对话框:让用户选择change directory还是add to path,选择“add to path”.然后程序会自动跳转到matlab命令窗口(command window)并显示提示信息:Are you sure that the images to be calibrate in current directory? [y]/n :让用户确认当前目录是否包含待标定图像数据,输入'n'终止程序运行,用户可将当前目录设置为包含待标定图像数据的目录再次运行calib_gui.m。
若输入'y'弹出对话框:让用户选择模式,有两种可作选择,一是Standard模式,一是Memory efficient模式.注意:若当前目录不包含待标定图像数据而用户又输入‘y’,那将导致程序进入死循环,若出现此情况,需重启MATLAB程序!!!并在命令行窗口显示当前工作目录下的文件列表。
Standard模式下所运行的图像数据会驻留在内存里,因而可以减少读取图像的操作,但如果需处理的图像数据过多,可能会造成内存泄露,Memory efficient模式下图像数据在需要的时候才被读入内存。
二者选择其一后进入同一个标定工具箱操作界面。
在此界面可完成标定的各个步骤。
首先读取图像数据,点Image names按钮,程序转入命令行窗口等待用户输入待标定图像的basename.Basename camera calibration images (without number nor suffix)-->如果当前目录下有图像文件:Image1.tiff Image2.tiff ... Image10.tiff 则应输入Image.程序继续等待用户输入图像格式:Image format: ([]='r'='ras', 'b'='bmp', 'f'='tiff', 'p'='pgm', 'j'='jpg', 'm'='ppm')-->由于我的计算机里图像数据的格式为tiff,故输入'f'。
matlab优化工具箱的使用
优化工具箱的使用MATLAB的优化工具箱提供了各种优化函数,这些优化函数可以通过在命令行输入相应的函数名加以调用;此外为了使用方便,MA TLAB还提供了图形界面的优化工具(GUI Optimization tool)。
1 GUI优化工具1.1 GUI优化工具的启动有两种启动方法:(1)在命令行输入optimtool;(2)在MA TLAB主界面单击左下角的“Start”按钮,然后依次选择“Toolboxes→Optimization→Optimization tool”1.2 GUI优化工具的界面界面分为三大块:左边(Problem Setup and Results)为优化问题的描述及计算结果显示;中间(Options)为优化选项的设置;右边(Quick Reference)为帮助。
为了界面的简洁,可以单击右上角“<<”、“>>”的按钮将帮助隐藏或显示。
1、优化问题的描述及计算结果显示此板块主要包括选择求解器、目标函数描述、约束条件描述等部分。
选择合适的求解器以及恰当的优化算法,是进行优化问题求解的首要工作。
✧Solver:选择优化问题的种类,每类优化问题对应不同的求解函数。
✧Algorithm:选择算法,对于不同的求解函数,可用的算法也不同。
Problem框组用于描述优化问题,包括以下内容:✧Objective function: 输入目标函数。
✧Derivatives: 选择目标函数微分(或梯度)的计算方式。
✧Start point: 初始点。
Constraints框组用于描述约束条件,包括以下内容:✧Linear inequalities: 线性不等式约束,其中A为约束系数矩阵,b代表约束向量。
✧Linear equalities: 线性等式约束,其中Aeq为约束系数矩阵,beq代表约束向量。
✧Bounds: 自变量上下界约束。
✧Nonlinear Constraints function; 非线性约束函数。
