说明：  结构振动反应。在强烈地震波德作用下，2个自由度相对位移和绝对加速度的反应，考虑了阻尼的影响。(struture response due to ground motion.during a big ground motion,one 2 degree of freedom-structure s relative displacement and absolute acceleration response.consider damping raion.)

说明：  matlab课件(matlab Courseware)

matlab函数scaleif，用于改变度量，详见英文描述( function sim = scaleif(im, newMin, newMax, oldMin, oldMax) Scales an image such that its lowest value attains newMin and it highest value attains newMax. OldMin and oldMax are not necessary but are useful when you don t want to use the true min or max value.)

数值积分工具箱 这些都是通用集成例程： quadg.m - 高Quad和QUAD8的准确性更换（1-D）quad2dg.m - 集成在一个矩形区域的2-Dquad2dggen.m - 比一般地区一体化的2-D- 超过ND超矩形区域quadndg.m ND集成(Numerical integration toolbox these are universal integrated routines: Quadg.m- Quad and QUAD8(1-D ) quad2dg.m accuracy replacement- integrated in a rectangular area of the2-Dquad2dggen.m than in the general area in the integration of2-D over ND super rectangle quadndg.m ND integration)
