Plot vectors of different size in Matlab












0














Let's assume I have tvector= 1:15 and I have two other vectors : X of size 15, each element of X relates to the corresponding element (element of same index) in t ; and Y of size 5, each element of Y corresponds to t=3,6,9,12,15.



How can I plot Xand Y on the same plot w.r.t. t, though X and Y does not have the same length (especially Y is not of same length as t)



Thanks

          Without an example of what you are trying to achieve, in code, we have to guess at your exact intentions.



          However, one option could be to plot a sub-selection of t against Y, something like this (using the values from your example):



          plot(t, X, t(3:3:15), Y)


          Of course this assumes that your values are actually spaced like your example.



          Another option could be to use NaN values as placeholders in the Y vector, to make it the same length as t. You may have to use markers (e.g. 'o') in that case.



          The best approach really depends on the context.

                    Image
                    Monofisismo (do grego: monos - "único, singular" e physis - "natureza") é o ponto de vista cristológico que defende que, depois da união do divino e do humano na encarnação histórica, Jesus Cristo, como encarnação do Filho ou Verbo ( Logos ) de Deus, teria apenas uma única "natureza", a divina, e não uma síntese de ambas. O monofisismo é contraposto pelo diofisismo (ou "diafisismo"), que defende que Jesus preservou em si as duas naturezas. Historicamente, o monofisismo se refere primordialmente à posição dos que (especialmente no Egito e, em menor grau, na Síria) rejeitaram as decisões do Concílio de Calcedônia em 451 (o quarto concílio ecumênico). Os membros mais moderados entre eles, porém, defendem a teologia "miafisita", que se tornou a oficial para as Igrejas Ortodoxas Orientais. Muitos ortodoxos orientais, porém, rejeitam essa classificação, mesmo como um termo genérico, mas ele é amplamente utilizado na literatura históri...

                    Monumento 1, uma das quatro cabeças colossais encontradas em La Venta, com altura aproximada de 3 metros Olmecas é a designação do povo e da civilização que estiveram na origem da antiga cultura pré-colombiana da Mesoamérica e que se desenvolveram nas regiões tropicais do centro-sul do atual México durante o pré-clássico, próximo de onde hoje estão localizados os estados mexicanos de Veracruz e Tabasco, no Istmo de Tehuantepec, numa zona designada área nuclear olmeca. A cultura olmeca floresceu nesta região aproximadamente entre 1500 e 400 a.C., [ 1 ] e crê-se que tenha sido a civilização-mãe de todas as civilizações mesoamericanas que se desenvolveram posteriormente. [ 2 ] No entanto, desconhece-se a sua exacta filiação étnica, ainda que existam numerosas hipóteses colocadas para tentar resolver esta questão. O etnónimo olmeca foi cunhado pelos arqueólogos do século XX, e não devem confundir-se com os muito posteriores olmecas-xicalancas que ocuparam vários locais do México...
