matlab - What's wrong with the use of arrayfun and bsxfun? -

i want integrate function follows:

in code, define indicator function follows:

pconstfundingrange=[0:0.25:2,inf];  pconstfunding=[0,tempfundinginitialpara,0]; % note tempfundinginitialpara constant each interval)   fundinginitial=@(t)...     arrayfun(@(s)pconstfunding(find(s<pconstfundingrange,1,'first')),t); 

with function defined, define function: integral of fundinginitial:

fundinginitialterm=...     @(t,t)arrayfun(@(s1,s2)integral(fundinginitial,s1,s2),t,t); 

my goal enter 2 vectors: vec1=[1,2]' , vec2=[0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9] , compute integral of given function f(s) follows:

hence, use following code:
bsxfun(@(t,t)fundinginitialterm(t,t),vec1',vec2)

however, outputs following error message:

error using arrayfun
all of input arguments must of same size , shape.
previous inputs had size 1 in dimension 1. input #3 has size 41

how solve problem?

this way integrals can computed:

f= @(s) sqrt(s); vec1=[1,2] ; vec2=[0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9]; [v2,v1]=meshgrid(vec2,vec1); arrayfun(@(low,up) integral(f,low,up),v2 ,v1)
