關(guān)于matlab使用 和瑞利散射的去除 已有1人參與

請(qǐng)問一下蟲友們,誰(shuí)會(huì)使用matlab去除三維熒光中的瑞利散射,請(qǐng)賜教,非常感謝。 我查閱了相關(guān)的文獻(xiàn),看到一篇是用delaunay三角形內(nèi)插值去除的,但是沒有看明白。如果過有誰(shuí)會(huì)用的話也請(qǐng)私密我。非常感謝。 |

我不是太明白這段程序?qū)?shù)據(jù)輸入格式的要求。那按照它的要求應(yīng)該是什么樣的?因?yàn)槲夷壳皵?shù)據(jù)輸入運(yùn)行的時(shí)候總會(huì)出錯(cuò)。出錯(cuò)在一段這樣的程序“Q=isnan(X.data)”給出的解釋是“NaN element at the original data due to emission out of spectroscopic instrumental range”似乎是說由于發(fā)射波長(zhǎng)超出了光譜儀器的范圍,NaN元素存在于原始數(shù)據(jù)。這個(gè)我理解不了,是我的發(fā)射波長(zhǎng)范圍有問題?我看了eemscat的程序也沒看出什么結(jié)果來,我程序方面的認(rèn)知有限 發(fā)自小木蟲IOS客戶端 |

不知道你會(huì)不會(huì)matlab,會(huì)的話程序里都有說明,仔細(xì)看下,不會(huì)的話就得改改了 function [EEM_correct,EEM_Cutted_rrr2]=eemscat2(X,MissRayleh,MissRaman,MissRayleh2); 函數(shù)名2應(yīng)該去掉改成eemscat 說明里的用法Example: % NewEEM = eemscat( X, [20 20], [10 10], [10 10]); % Data Rayleigh RamanWidth 2.orderRayleigh 主要用這句改改你的東西就行 EEMSCAT for removing Rayleigh and Raman scattering from fluorescence % EEM data and interpolating the excised areas. % % INPUT: % X X-array of EEMs. X is size IxJxK, where I is number of % samples, J emissions and K excitations. X has to be a % dataset object where the axisscales contain wavelengths. % You can convert an array to a dataset doing % X = dataset(X); % X.axisscale{2} = EmAx; % The emission wavelengths (nm) % X.axisscale{3} = ExAx; % The excitation wavelengths (nm) % % OPTIONAL INPUT % RayeleighWitdth % RayeleighWitdth is a two-element vector defining how many nanometers % to the left and right of the Rayleigh center is removed. Use % [0 0] to avoid removing. Default if not given is [25 25]; % % % RamanWidth % As above but for Raman. Default is [0 0]. Assumes water samples % (for the position of the Raman scatter) % % Rayleigh2Width % As above but for second order Rayleigh scatter. Default is none % [0 0]. % % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % Example: % NewEEM = eemscat( X, [20 20], [10 10], [10 10]); % Data Rayleigh RamanWidth 2.orderRayl % % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % OUTPUT: % % NewEEM EEM data with interpolated areas. % % Additional optional output % EEMNaN EEM data with missing data rather than interpolated values % |

別人寫的就是這個(gè)格式,你按他的調(diào)用就行。 % INPUT: % X X-array of EEMs. X is size IxJxK, where I is number of % samples, J emissions and K excitations. X has to be a % dataset object where the axisscales contain wavelengths. % You can convert an array to a dataset doing % X = dataset(X); % X.axisscale{2} = EmAx; % The emission wavelengths (nm) % X.axisscale{3} = ExAx; % The excitation wavelengths (nm) % |
